####Folks like Isaac Newton assumed God started the world and left the machinery untampered, except perhaps for an occasional miracle.####
Science says nothing one way or the other about God's existence. Therefore it was not unscientific for Newton to suggest that God started the universe and set up its laws.
####But cosmology, geology, physics and biology are ongoing, not occasional. If you believe the processes of biology are subject to whimsical fiddling, you cannot do science.####
True, but asserting that God set the laws of physics, biology, etc. up, and in fact created the medium in which they exist, is not unscientific unless you define science as EXCLUDING the possibility that God exists.
Newton was a scientist, regardless of his religious beliefs. He was a scientist because he employed empirical methodology and reasoning. He looked for natural causes rather than miracles. He assumed the regularity and consistency of natural phenomena.
Anyone doing this is doing science, regardless of beliefs. Science does not comment one way or the other on the existence of God.
I fail to see what point you are making.
