I think the thing is, is that if there was a beginning - even if - there would still be multiple ways of interpreting it.
Like the blind men examining the Elephant: it is not clear to any of them, that the one Elephant is like the many animals (animals, that they see in the Elephant - the snake for the trunk, the rhinoceros for the tusk, the hippopotamus for the feet, the horse for the tail).
Genesis looks at perfection, Ezekiel looks at the faith, Jesus looks at male and female, John looks at the word - all these things are interpretations of the same beginning and each interpretation serves its own purpose. We do not look at the perfection of the beginning and say "I have no need of giving it a word"; we do not look at the faith and say "I have no need that it be male and female" - all these things are inter-related; the world looks at us and says "they have an opinion, about the beginning, I will have one too" but they do not consult God, as to what interpretation was needed.
So I think it will be evident, that Man is in need of God, whatever He discovers about the beginning - simply because it is too complicated to graft everything, on the same foundational knowledge. There may be successive grafting, as with the passing of the time of History, but there will be no conclusion that men ought to stop thinking of the beginning, in anything other than a "particular" way. I would even stand to benefit, if there was just one interpretation, but I don't seek it, because I see Wisdom, in how God has set out the greater point that can be made, when you trust His timing.
And that is basically it, if it exists in time at all, it has a beginning and if it has a beginning, the timing of that beginning, is more crucial than the interpretations of it!
