How do you think life started?

Question

I want real answers and not bed time storys like the bible.

Answer 1

My favourite theory, since it is the best thought through in terms of evidence and implications that I have yet to read is the Cairns-Smith theory that the first self-replicating systems were mineral crystals. The idea is that crystal defects of growing clay crystals are a very simple information transfer system. Any crystal structure that allows faster growth in a given environment will tend to outgrow any competing crystal types. Any adoption of available chemicals that permits faster crystal replication will be favoured by a process of entirely natural selection. This is no more controversial than saying that, in a given environment, faster growing crystal structures will grow faster. A growing crystal system will use compounds from the solution diffusing through it rather like a living organism may extract nutrients from its environment in order to grow and reproduce. Equally, chemicals removed from the crystal environment will be washed away rather like the waste products from an organism.

The theory is that over a long period of time this basic sytem, that already has some parallels with life, starts to incorporate increasingly complex organic compounds as well as catalysing their reactions into other structures. It is well known that clay minerals can do this and there is and has been a lot of mud out there. The organic-inorganic structures that are most successful at growing and reproducing will grow to dominate over less effective structures. The theory is that this process of evolution eventually led to the first life, but the exact point at which this transition occurred is a grey area which depends upon how you define life.

Of course, there is quite a lot of inorganic chemistry involved in life (e.g. bone and teeth are largely hydroxyapatite, we need iron to form haemoglobin) which might be a residue from our inorganic origins?

Answer 2

All kinds of organisms exist in outer space. They cannot develop fully because of the extreme temperatures of space. As space dust collides and gathers in swirling clouds, eventually forming comets, meteors or planetoids, the organisms can attract new chemicals. This in turn brings together more chemicals which develop into new, complex cells.
These organisms can live on comets etc for millions of years. Eventually these space rocks will collide with planets, such as our own. As they are released during the collision, the cells develop resistance. After millions of years, the cells natural instinct is survival, to breed and become stronger. If the conditions are favourable, like on Earth, the cells will become a living organism that takes on the planets chemistry. millions of years later, they change by natural selection to become the host of the World they have landed on. Mutations, like the irregular cells they once were in the primordial space dust, enhance the survival chances. These mutations occur regularly as the planets chemistry balance changes over time. The sequence is stored to replicate the make of the planet, thus the balance is corrected so the original cell passes on its information.
Part 2 tomorrow.

Answer 3

When atoms move at different powers of the speed of light in quantumnical units, laws are created. We just so happen to live in a speed zone where gravity, electromagnetism, and all those other laws exist. Life, however, is not a force. In my opinion, I believe in memory wake euroty (my very own theory), where life was created to support life itself. If my theory is correct, everyone has lived an infinite amount of times as the same DNA
and is living right now as an infinite amount of lives spread across the universe. We do not know this because we purposely block out or forget these facts for our minds can't comprehend and cope with knowing everything. So life was created by no logical reason since it wasn't created at all.

Answer 4

No mere human will ever find out the whole truth of the universe. It's sad that some people think they know for a fact that god created it.

To the christians: He said no bible theory's. So why have you answered this question? He didn't want your opinion.

Answer 5

Life started on EARTH at the bottom of the ocean next to volcanic vents spitting out chemically rich hot water. During this time there was no photosynthesis.

Answer 6

I believe that God made life start. Yes, you may say life started from bacteria, but where did this bacteria come from? It can't just pop out from no-where. Then you might question me asking: So how do you say God was there by Himself? Because there must be a greater force out there which has no beginning.

Answer 7

An old answer to creationists, but still valid:

Who created the world? God did.

Who created God? God was there in the first place.

So why not say the world was there in the first place, and cut out God as unnecessary.

Answer 8

I have a few;
One it was pounded out of the earth rocks pulverize crating a gas that formed liquid turn into the sea a satellite put into orbit to crate gravitational tides and air filtratration.
# 2. some alien was piss at another space traveler and crated a replica of what he translated to be his planet to trap him and maroon him on this planet.

Answer 9

If you think the Bible is a bedtime story, I feel sorry for you. Open your mind and you might learn something.

Take the cover off your computer and look inside. Do you see the complexity in that small box? Do you think there's any way that something that complex just "evolved" without any external influence? Now consider the universe - millions of galaxies, stars, planets and (possibly) civilizations. Do you suppose there's any way that it just "happened"? Suppose the Big Bang is correct. Who lit the fuse?

Some intelligent force must have set it all in motion. Call that force what you wish...I call it God.

Answer 10

i think life on the earth catually can from deeps space. most likely it arrived on earth on a comet.
