But your argument contradictrs itself, if the universe was made by the collision of strings that means that it did start of with SOMETHING, god however is not bound by the three dimensions of space or the single dimension of time, this would explain how god has existed forever, and in his independance created the universe in perfect scenarios. The Big Bang. before the 19th century atheists readily denied the big bang thoery and instead believed in the infinite expanse of time of the existance of the universe. The Big Bang theory suggests that the universe did indeed have a begining as explained in the holy books thousands of years ago. So what you have a theory, it only half functions anyway, and even if it does, so does the theory of creation, just because you prove one thoery right doesn't give you the chance to exclude the other.
Foolish atheists... i'm sick of you r pathetic attempts to prove Big Bang, it is inevitably impossibe to prove the infinite manner of the universe by fundementals that are bound by finite limitations, mathematics , science. Besides you have provided no evidence but only a meagre idea.
