My topic title quotes Genesis 1:1 which is where the opening post launches from. You don't get to redefine my topic to suit your 'argument' Fisherman.
I did not do that. First, I responded to your OP then I responded to other posters. You did not set parameters in your OP- Unless you are ridiculing Genesis 1:1, but you deny doing so by saying that your question is not rhetorical (for example: "Why are you so stupid ?"is a rhetorical question) The only logical response to any question about the God of the Bible is from the Bible and the only logical explanation about a Bible verse is also from the Bible I thought you knew that. Science is an approach to measure the relationships between mass, energy, space, time (physical and natural world). If you want to launch rocket to get to the spirit realm, you are wasting your time.
The Bible is silent on God's pre heavenly existence so the debate, by necessity, is not "about what the Bible says".
What do you mean by pre-heavenly existence? The book of Job describes God existing before Gen1:1 and so do other books of the Bible. I think that I have already answered your question in my other posts. The problem is that you seem to limit God as if he needs a heaven to exist in. The human mind can only understand God in terms of substance that the human mind can grasp. God is beyond that. Just so you understand, science deals with the physical and the natural.
