The "Big Bang" is not repeatable, and therefore cannot be proven scientifically. What can be done is to examine the evidence, and then a case can be made for evidence pointing to a possible scenario. If we think about the Big Bang, what do you think it would look like? Would it be a spontaneous explosion of all matter, assembling itself into galaxies, stars, planets, elements, and ultimately life? Would that look anything like what the Bible describes as God saying, "Let there be light," etc. and all things come to be at once? Your thoughts?
