Answer:
[Note of serious caution: The three theories listed here are among the three best known, perhaps, although the static state theory, preferred by Einstein, is not given much credence today. The question as given implies, inadvertently or otherwise, that you must choose the correct theory from the three given. There is no reason whatever to believe that there can never ever be credible theories added to the list. It is NOT a matter of saying: Pick one of these three, they are for all time the only choices you can ever have on this question. Another way of stating this dangerous logical pitfall would be: If I can demonstrate flaws or failings in any two of these, the remaining one MUST be correct.]
Big Bang.
Static Universe - (It has always been here)
Genesis - Old Testament.
