Assuming the observer affects the observed (recent work in quantum mechanics challenges this or at least tries to explain/trivialise the effect away as being an artifact but let’s keep the accepted model for a while) if matter arises from consciousness (probability wave collapsed into existence) then consciousness did not arise from matter. If there were no observers matter could not arise so the mind (observation) of God was necessary for the universe’s matter to be created and His constant observation sustains it (not ours). Somewhat as the Bible says.
God speaks things into existence. Words express thought. It seems reasonable that God thought all the arrangements necessary for the universe, then expressed them as the universe.
There is likely and strangely more to it than that – a relationship between the numbers and meanings of the Hebrew alphabet and fundamental qualities of the universe may exist and if explored could bring much fundamental insight into physics – at an instrumentalism level.
So “I think therefore I am” is a trivial statement of existence compared to “He thinks therefore we are” that allows all of us – even Mr Kant who would say it doesn’t – such navel gazing.
The message of the Bible of course moves quickly on from how we came to exist to what a wonderful purpose we should put that privilege to.
