To start, I want to clear up some simple, misinterpretations that some of you may or may not have made, probobly due to the lack of information. First of all, Buddhists do not worship the Buddha, and the Buddha was not a God. He was just a teacher and an inspiration to his followers. He was someone who had obtained "enlightenment", or been awakened to the way that all things are. Kinda like a "meaning of life" sort of deal. Which is much more complex than many would expect. At first when Buddha discovered this, after meditating for several days, he believed it was pointless to try and teach someone what he has obtained, that his thoughts couldnt be explained through the means of words. but he was soon convinced when he came across a wondering holy man told him that "some people just have a little dust in their eyes, and can be helped if someone could wipe some of it away."
Now for the basic explination of how Buddhism works...
Buddhists consider it the job of scientists to explain origins of the universe and life. So there is no contradiction with scientific discovery. Although most buddhists say the world creates and recreates itself millions of times every fraction of a second.
After Death, as Buddhist would say that there is no transmigration of individual souls, but through the law of karma, a persons wholesome or unwholesome
