Archive for the ‘evolution of life’ Category

In the previous article we talked about the evolution of life on earth and now in the second article we will talk about the evolution of Human beings assuming the 8th theory as base.

Earth is our real home?

We were sent here for some purpose?

God really exists?

Gods we worship are aliens?

Similar questions arises & we are unable to quest our thirst so moves on. But now on ask me anything & I’ll give you the answers.

I know it is hard to digest that earth is not our home, it is strange to hear but maybe it’s true. Some scientists have argued that life originated on mars, due to a mineral found in Martian meteorites, thought to be crucial to the genesis of life. In another discovery DNA and amino acid molecules found in an interstellar gas cloud. Which means that important building blocks for DNA and amino acids can ‘seed’ newly-formed planets with the chemical precursors for life. Some suggests that we may not have evolved alongside other life on Earth – but arrived from elsewhere, brought here by aliens as recently as a few tens of thousands of years ago that’s why we are still adopting the environment of earth. You can’t find a single person who is 100% fit and healthy and not suffering from some (perhaps hidden or unstated) condition or disorder.

American ecologist Dr. Ellis Silver says

“Mankind is supposedly the most highly developed species on the planet, yet is surprisingly unsuited and ill-equipped for Earth’s environment: harmed by sunlight, a strong dislike for naturally occurring (raw) foods, ridiculously high rates of chronic disease, and more. Plus there’s a prevailing feeling among many people that they don’t belong here or that something “just isn’t right”.

So based on my study let’s suppose that we doesn’t belong here then what is the purpose of humans here on earth. We were sent here for some purpose?

Certainly I cannot answer this question but definitely we are not send here for breeding & bleeding. Almost every human

follows a routine in his/her life & then die so why are we here if we all have to die at some point?

According to Bible God created man and created him for his glory (Isaiah 43:7). Therefore, the ultimate purpose of man, according to Bible is simply to glorify God. The harder question is that what does it look like to glorify god? In Psalm 100:2-3, we are told to worship god with gladness and know that lord is god. Ït is he who made us, and we are his: we are his people, the sheep of his pasture.” Part of what looks like to glorify god is to acknowledge who is and praise & worship him.

According to Hinduism, there is not just one purpose of life but four:

  1. Dharma: full filling one’s purpose
  2. Artha : Prosperity
  3. Kama : Desire, sexuality, enjoyment
  4. Moksha : enlightenment

Aspect of dharma is also paying five debts.

  • Debt to gods for their blessings; paid by rituals and offerings
  • Debt to parents and teachers; paid by supporting them, having children of one’s own and passing along knowledge
  • Debt to guests; repaid by treating them as if they were gods visiting one’s home
  • Debt to other human beings; repaid by treating them with respect
  • Debt to all other living beings; repaid by offering good will, food or any other appropriate help

Ultimate end of every Hindu’s life is moksha which can be understood in a variety of ways: liberation from rebirth, enlightenment, and self-realization or union with god. This is considered highest purpose of life, although very few can achieve it.


According to Islam the whole purpose of life is to worship the almighty Allah (GOD) although there are 5 pillers of Islam, which are acts of worship

  1. Professing your faith, Shahadah : There is no god but Allah , and Muhammad is his messenger
  2. Prayer, Salat : To pray in a proper way, five times a day
  3. Giving to charity, zakat : To give money to charity to benefit the poor and needy
  4. Fasting, sawm : To fast during the month of Ramadan
  5. Pilgrimage, hajj : To make a pilgrimage to mecca, at least once in life

“So according to three major religions we are created by god & have to worship them until we meet almighty god.”

“Who is God”

We will discuss it in the next article. Till then think and feel free to ask anything.

Sometimes the question arises in the mind that why do we even exist in the world ?

How can life form only on earth ?

When did the life began on earth ?

Do we belong here ?

Similar questions arises & we are unable to quest our thirst so moves on. But now on ask me anything & i’ll give  you the answers.

Life on Earth began more than 3 billion years ago, evolving from the most basic of microbes into a dazzling array of complexity over time. But how did the first organisms on the only known home to life in the universe develop from the primordial soup? There are several theories about evolution of life lets read them first.

  1. Electric sparks can generate amino acids and sugars from an atmosphere loaded with water, methane, ammonia and hydrogen, as was shown in the famous Miller-Urey experiment reported in 1953, suggesting that lightning might have helped create the key building blocks of life on Earth in its early days. Over millions of years, larger and more complex molecules could form. Although research since then has revealed the early atmosphere of Earth was actually hydrogen-poor, scientists have suggested that volcanic clouds in the early atmosphere might have held methane, ammonia and hydrogen and been filled with lightning as well.
  2. The first molecules of life might have met on clay, according to an idea elaborated by organic chemist Alexander Graham Cairns-Smith at the University of Glasgow in Scotland. These surfaces might not only have concentrated these organic compounds together, but also helped organize them into patterns much like our genes do now.
  3. The main role of DNA is to store information on how other molecules should be arranged. Genetic sequences in DNA are essentially instructions on how amino acids should be arranged in proteins. Cairns-Smith suggests that mineral crystals in clay could have arranged organic molecules into organized patterns. After a while, organic molecules took over this job and organized themselves.
  4. The deep-sea vent theory suggests that life may have begun at submarine hydrothermal vents, spewing key hydrogen-rich molecules. Their rocky nooks could then have concentrated these molecules together and provided mineral catalysts for critical reactions. Even now, these vents, rich in chemical and thermal energy, sustain vibrant ecosystems.
  5. Ice might have covered the oceans 3 billion years ago, as the sun was about a third less luminous than it is now. This layer of ice, possibly hundreds of feet thick, might have protected fragile organic compounds in the water below from ultraviolet light and destruction from cosmic impacts. The cold might have also helped these molecules to survive longer, allowing key reactions to happen
  6. Nowadays DNA needs proteins in order to form, and proteins require DNA to form, so how could these have formed without each other? The answer may be RNA, which can store information like DNA, serve as an enzyme like proteins, and help create both DNA and proteins. Later DNA and proteins succeeded this “RNA world,” because they are more efficient. RNA still exists and performs several functions in organisms, including acting as an on-off switch for some genes. The question still remains how RNA got here in the first place. And while some scientists think the molecule could have spontaneously arisen on Earth, others say that was very unlikely to have happened.
    Other nucleic acids other than RNA have been suggested as well, such as the more esoteric PNA or TNA.
  7. Instead of developing from complex molecules such as RNA, life might have begun with smaller molecules interacting with each other in cycles of reactions. These might have been contained in simple capsules akin to cell membranes, and over time more complex molecules that performed these reactions better than the smaller ones could have evolved, scenarios dubbed “metabolism-first” models, as opposed to the “gene-first” model of the “RNA world” hypothesis.
  8. The theory on which i believe the most says : Perhaps life did not begin on Earth at all, but was brought here from elsewhere in space, a notion known as panspermia. For instance, rocks regularly get blasted off Mars by cosmic impacts, and a number of Martian meteorites have been found on Earth that some researchers have controversially suggested brought microbes over here, potentially making us all Martians originally. Other scientists have even suggested that life might have hitchhiked on comets from other star systems. However, even if this concept were true, the question of how life began on Earth would then only change to how life began elsewhere in space.

So here ends my first article so what do you think? Which theory do you believe in? Tell me & ask anything.
