D wiltshire;
I feel I can beleive in evolution and still beleive in God.
Yup. But what do you mean by god?
My postulation was if both thing were true then this is my conclusion.
Yeah, but your postulate revealed (without being rude), that before you get round to postulating you'd better do some learning. If you had a high school or sophomore level knowledge of the Sciences, you wouldn't have asked the question as you'd know it was silly to anyone with a decent level of science education. I'm not saying you are dumb, just you need to learn. Let's look at it;
If evolution is true and God doesn’t exist, and all matter always existed,
Wrong. Matter has not always existed. The Universe started as a singularity (a small, as in REALLY SMALL, subatomically small) point which went bang. The best understandings seem to indicate the 'begininning' was more like a U than a V, as in the process which lead to the big bang was a gradual process (until the bang itself) rather than starting all of a sudden at a certain instance... it was like a paper warehouse exploding in flame after a small fire raised the temperature inside to 471 degrees F... a cascading chain reaction, built on the fabric that our space-time is built on, a zero-point energy field (where there is LOADS of energy, but just happens to be an average of zero; think of fizzy water).
Now, my level of understanding of the above physics is slightly better than your understanding of evolution I'd say, but I fully admit that's a vert layperson explination, so any one who can do better I salute and open the floor to, but, matter is ALL from the big bang, and that can be dated, so matter did not exist for ever.
and life keeps adapting and getting more and more advanced, conquering all problems set before its existence.
Wrong in particular, but in general true.
If you do anything too extreme (like drop a very large asteroid into the atmosphere at high speed), then you exceed the adaptability of most species, at least the ones with more than one cell... ). You can but an infinate number of goldfish and take them out of water one by one and put them on your coffee table and they will all die, by drowning in the air.
Less extreme things, like AIDS, as a previous poster bought up, can be overcome by adaptation; already there are towns in Africa where about a third of the protitutes do not get infected by AIDS, despite exposure on a regular basis. Slow climate change will kill those without the required fitness and concentrate the genes giving the fitness for the new climate in the surviving population.
Then life should have already filled the entire universe and advanced to the point of never dying.
Wrong. Life expands to fill niches. Life obeys physics. It is possible, I suppose, that a species would develop immortality, but I doubt it would be through evolution. Evolution is a blind genius. It can get round virtually any problem, but cannot get round problems that aren't there.
I need to explain that; there is no need to live forever to pass genes on. Therefore this feature is not selected by evolutionary mechanisms, as evolutionary mechanisms revolve around the passiing on of genetic material.
Also, vaccuum is a niche that may have a life form in it now, or one day, but it would be weird shit life, sustained by stellar radiation or zero-point energy, or perhaps interstellar gases.
As the Universe consists of mostly vaccuum, seperating the more desirable areas, life cannot 'fill the entire Universe'.
Also, if you are seeking for 'truth', you have lost the way already; you say;
I'm trying to be fair and open minded, though I'm way more in favor of beleiving in God's existance.
That is niether fair nor open minded. You cannot pretned to search for truth and really be looking for god, because all you will do is, most probably, is to find god even if it's not there.
And;
What if all that God required of us, is to show we want eternal life in some tangible way that will indicate we really wanted it, and then, and only then, grant it to us?
This would be fine if an intelligent creature could ascertain this was god's will without doubt. God's exitence or desires cannot be ascertained without doubt. Therefore, either it doesn't exist, or it has no desires regarding our actions, or it's an asshole playing games.
Keep on rocking in the free world...
