If bible, koran, torah and other holy scriptures are wrong this will not prove that there is no God. If there is a God there is no way we can prove his existence if he don't want to. Our civilization is still very young, still many things we cannot explained.
Sure, there is no way to prove god doesn't exist; but if we can continually make progress in our quest for knowledge without such a concept, why bother with it?
We really need to find out what God is about. Why? Because we don't really understand death, and certainly not life.
Our progress in our quest for knowledge has shown us one basic thing. That basic thing is that the deeper we go in the quest, and the more knowledge we find, the more we see that we are only scratching the surface of what there is to find out. And the more we find out, the more we realize that our scratching the surface is a much smaller scratch that we had thought previously.
Here is what I mean. If a pool (billiards) player is a super-good player, he might be able to accurately call out the pocket through 5 balls being ticked to get the final ball into the pocket he called. For example, he ticks the Cue ball, which ticks ball 1, which ticks ball 2, which ticks ball 3, which ticks ball 4, which knocks ball 5 into the proper pocket.
Now, think of how God played pool with this universe. God created a whole bunch of Cue balls (electrons, protons, neutrons, photons, multitudes-of-other-particles), and sent them flying so that they would tick each other. And God did it so well that after thousands of years these "ball"s are still "ticking" each other in ways that produce complexity, complex intelligence in people, and all kinds of order in the universe. There is even order in nuclear explosions, in the way all the subatomic particles all hit each other exactly according to the laws of physics.
In other words, if we don't find God, or if He hasn't allowed us a way to find Him, we are truly lost. Why? Because it might take thousands or millions of years to get all the knowledge that it takes to find out what things are all about. And that's only if things keep on going as orderly for us as they have in the past. And besides, experience shows us that in all our knowledge, we haven't really found any ways to extend life to any practical length. After all, the Hunzas and the people of Vilcabamba, Ecuador, live lives on the average longer than we do with all our medicine.
This means that after thousands or millions of years of scientific investigation, countless numbers of people will have died, including you and me.
