Can anyone of you give me a very very brief acount of evolution and its different stages, please! e.g. from the big bang to molecules to fish to land animals and plants to monkeys and then to man

im a computer nerd.. so i dont know. i think it goes like single cell-multicellular-water organism-very very simple fish-a little more complicated fish-land/aquatic organism-lizard type things-just more and more involved lizards-dinasours-mammals, like pre roden type things-more evolved mammal-monkey-smarter monkey-dumb human-human-me :) and i think it is because they adapted to fit their enviroments better, and their populations increased due to them being well adapted, or an over-all increase to all. like the large increase of oxygen that happened.

Well, that's a bunch of different things here. The Big Bang is separate from evolution, as is abiogenesis. The fish we have today could not possibly evolve into land animals, plants cannot evolve into monkeys and humans did not descend from monkeys. Modern monkeys/apes are distant cousins to humans. All the things you mentioned did not evolve one to the next, but they have a common ancestor.
This site should help explain the details.

I'm astonished to find that you asked this question at the same time you rattled off a series of supposed problems with the theory of evolution.
Yet here you clearly admit you don't understand even the basics of the theory!
There's nothing wrong with that. That's admirable to ask for information you lack.
But if you clearly lack such basic information, why do you seem so intent on discrediting Evolution in your concurrent questions?
Here's a tip: Learn about evolution from scientific sources.
Then attempt to criticize if you find it lacking.
But you have to learn FIRST.
My favorite web links for understanding the fundamentals of evolutionary biology is below.
Mind you, this is biology only. You also ask unrelated question about cosmology and the Big Bang, which has nothing to do with biological evolution! You're also talking about abiogenesis, the origin of life, which is related to evolutionary biology but is not part of the Theory of Evolution itself.

Random mutation in gentic code happen n every generation. A mispelling of nucleotide sequences. These mutations cause traits to appear that either help or hurt an organism's chance at survival in it's enviornment. Over time, these mutations can cause an entirely new species to appear.
How did this all start? 3.8 billion years ago, the earth was more unlike today's atmosphere... there was no nitrogen, free oxygen or any thing... just methane (CH4), Ammonia (NH3), and water (H2O). The ultraviolet radiation and lightening strikes caused these chemical soultions to randomly fall apart and reassemble themselves into increasingly complex sequences until the first RNA sequences were formed... these made amino acids and eventually, the DNA double helix that we hear so much about. One this happened, it was all gravy. DNA can make copies of itself with the similar substances around it. This, plus 4 billion years of evolution equals you.

What a friendly title =)
The main idea behind genetic evolution is that, a group of animals are living hapily in an enviornment. All of a sudden, the enviornment changes DRASTICALLY. Now...know that in genetics there are differences between every single one of the organisms in that species. So, with this drastic envionmental effect affecting the species, about 95% of the species die. the remaining 5% have the Genetics that make them different enough to survive the change. Now these 5% re-populate the population and voila! Slightly different species.

The answer to your question is far too complex and lengthy for this venue. Check wikipedia and some science books on evolution. You will learn an immense amount.

very brief?
nothing all day long, the sun in the last hour, and life in the last second. ok?
and read this.

God exist out side of time.
He is the master physicist .
