God created us, in his image.
Its no different from an evolutionists theory, only theres more evidence to back this view up. After all, and evolutionist can argue we came from apes, but go back to the very begining, before all this evolution started. What caused the Big Bang? Was it an accident? Again, that takes faith to believe it was an accident, just as it does to believe that someone caused the Big bang to happen, if the Big bang did.
But ultimatly, if you argue the Universe has always existed, then unless you too have always existed, you cannot argue that your theory of an eternal universe is fact, you must take a leap of faith to say that everything has always been there and will, because you werent there at the begining.
Although the faith is different from one who has a religion, its still the common leap of faith, as you are not 100% sure that your view is correct.
Being a Christian, and the fact that I konw Christ actually existed, and what was written about him in the collections of eye witness accounts, are true, and thus his identity is as he claimed, then I have 100% assurance in that leap of faith ive taken to trust him.
An evolutionists faith is ultimatly subjective, as there is no solid evidence of what happened at the begining in their view, and i reckon with in a couple of hundered years, the view will be discredited, just as every other major world view has been in earths history (egypt and their beliefs anyone? Romans and their pluralistic beliefs?)
