LOL.
God is
Yes
God is all there is
Provisionally, as I am, but I am not God, but poetically, in the way of 'love is all there is', then yes.
God is the explanation for the unexplainable
No, that's the God of the Gaps.
Henry Drummond (19th c evangelic preacher) preached against those who point to the things that science can not yet explain: "gaps which they will fill up with God".
Ernest Barnes, the Bishop of Birmingham, discussing the Big Bang in 1933:
Must we then postulate Divine intervention? Are we to bring in God to create the first current of Laplace's nebula or to let off the cosmic firework of Lemaître's imagination? I confess an unwillingness to bring God in this way upon the scene. The circumstances with thus seem to demand his presence are too remote and too obscure to afford me any true satisfaction. Men have thought to find God at the special creation of their own species, or active when mind or life first appeared on earth. They have made him God of the gaps in human knowledge. To me the God of the trigger is as little satisfying as the God of the gaps. It is because throughout the physical Universe I find thought and plan and power that behind it I see God as the creator"
Dietrich Bonhoeffer:
"How wrong it is to use God as a stop-gap for the incompleteness of our knowledge. If in fact the frontiers of knowledge are being pushed further and further back (and that is bound to be the case), then God is being pushed back with them, and is therefore continually in retreat. We are to find God in what we know, not in what we don't know."
Charles Coulson (1955)
"There is no 'God of the gaps' to take over at those strategic places where science fails; and the reason is that gaps of this sort have the unpreventable habit of shrinking." and "Either God is in the whole of Nature, with no gaps, or He's not there at all."
G!d isn't some larger than life being made in our image
No
G!d is the theory of everything that scientists are seeking
Depends on what scientitst? Theologians are scientists. But if you mean the empirical-method branches of science, physics, maths (with an 's', because I'm a Brit, goddamit!) etc., then no, because they're looking for empirical answers.
