Please state the scientific posibillities of life's emergence in this planet/universe.

God created a large mass. Large mass exploded (see big bang theory). Universe was created. Got that strait from the Quraan.

Soth's simple explanation-

Don't know, wasn't there.

Although the theory "God created everything" sounds a little shallow and simple minded, why does something simple have to be discredited?! Some might argue that believing in God takes a whole lot of faith....but what is it then to believe the Earth and all living creatures are just victims of circumstance?

I suppose the people who are the least stupid are those who choose not to believe anything at all concerning the beginning of life, and let it remain a mystery. Because honestly, why does it matter? Life exists now, no use in pondering pointless questions of the past. Nothing can be gained from exploring such thoughts.

^The information could come in handy for calulating, say, the likelyhood of life in any given system. It's possible that that info could become a bit more than academic sometime in the future.

The most common hypothesis I know of (I know two) is that an electrical current such as lightning in a certain chemical soulution created a self-repilcationg molocule (not particularly DNA, mind you) that eventually evolved into life as we know it.

The much less known, and I think more likely, hypothesis is that DNA life evolved originally from a long chain of non-organic self replicating substances, such as crystals (really).

I'm quite aware that no-one can actually "prove" hypothesizes like this, but I stress that that's not really the point of looking into it.

Lessee.... Timeline:

1) There was nothing.
2) There was something really damned tiny.
3) The something really damned tiny exploded and created Protons and Neutrons and Electrons.
4) The Protons, Neutrons and Electrons got together and started making atoms.
5) The atoms got together and either fused to become larger atoms or created compounds.
6) The larger atoms clumped together and ran into each other and (over a really long time) became planets and stars.
7) On planets with water, clouds formed.
8) On planets with electromagnetic fields and clouds, storms occured.
9) The electricity of the storms, combined with ash and other imprities, caused the water to create amino acids.
10) The amino acids clumped together to become a cell.
11) The cell ate, and ate, and mutated, and ate, and replicated, and ate.
12) Eventually, there were a lot of cells, some more successful than others.
13) The successful cells learned how to connect themselves to other successful cells, becoming the first multi-celled organisms.
14) The multi-celled organisms grew, and ate, and mutated, and ate, and replicated, and ate.
15) Eventually, the multicelled organisms had mutated to the point where they no longer needed to remain in the water to survive, and moved to land to have less competition for resources.
16a) Photosynthetic organisms evolved into plants.
16b) Non-photosynthetic organisms evolved into herbivores (who ate the photosynthetic organisms) and carnivores (who ate the herbivores and each other).

Viola! Life!

that something really tiny had to come from somewhere. I beleive god created it.

Some thing damn tiny must be proven existnence, or how it became, some thing damn tiny was created by something else.

True, it had to come from somewhere.

Scientists who do not believe in god say that it was created in a manner similar to how 0=0 changes into 3=3. You simply add something to both sides of the equation. In this case, when enough matter was created to cause the "Big Bang". A similar amount of anti-matter was created somewhere else to cause the "Other Big Bang". The two exist at the same time and can completely cancel each other out, except that entropy refuses to allow them to. Hence, the universe continues to exist.

Interesting thought, but where did the something that added to the both side of the equation come from, even if there is equal number of matter and antimatter created, they still had to be coming from somewhere.

According to the theory I was told (I didn't read this. I used to get into long conversations while playing chess with a buddy of mine getting his doctorate in Physics) it is a reversal of the theory that when matter and anti-matter collide, they annihilate each other and only produce energy. In this case, all that existed before matter was nothing, literally. The creation of antimatter and matter universes comes from the theory that, given enough time, 1 + (-1) = 0 will come to pass. Meaning that 'eventually' a matter and an antimatter universe will be spontaneously created.

No, I don't understand it completely myself, this was said over a chess game in which I lost, so some of the details are sketchy.

Ah I see, cool

HelloTman16 · Post by **HelloTman16** » Fri Aug 01, 2003 7:14 pm

still takes just as much faith as believing in a god to begin with......deism vs. big bang......I choose deism

Fixer · Post by **Fixer** » Fri Aug 01, 2003 7:24 pm

yeah, I know. But as long as it's all theory, everyone just pick your favorite.
