Yep, it’s called ‘there’s stuff we still don’t know’.
He; like Nature; abhors a vacuum.
There MUST be a 'theory' for EVERYTHING; even if that means 4-5 of them do not quite fill the bill and conflict with each other.
Job 38 New International Version (NIV)
1 Then the Lord spoke to Job out of the storm. He said:
2 Who is this that obscures my plans
with words without knowledge?
3 Brace yourself like a man;
I will question you,
and you shall answer me.
4 Where were you when I laid the earths foundation?
Tell me, if you understand.
5 Who marked off its dimensions? Surely you know!
Who stretched a measuring line across it?
6 On what were its footings set,
or who laid its cornerstone
7 while the morning stars sang together
and all the angels[a] shouted for joy?
31 Can you bind the chains[b] of the Pleiades?
Can you loosen Orions belt?
32 Can you bring forth the constellations in their seasons[c]
or lead out the Bear[d] with its cubs?
33 Do you know the laws of the heavens?
Can you set up Gods[e] dominion over the earth?
