I don't think I have been off topic with anything I have written. But perhaps that is your latest tactic - pretending that someone who disagrees with you is off topic. But OK, let's "stay on topic" and look at the scriptures:
My argument about your evasion is solid, because there is no debate about phrases like "in the beginning". The gap idea never has denied that God created the heavens and the earth "in the beginning" per Genesis 1:1. With trying to assign other Scriptures with the word 'beginning' in them back to Gen.1:1, just because they have the word 'beginning', is vague and illogical, simply because that word is always in relation to an object it's tied to. In the case of Gen.1:1, it's about God's creation of the heavens and the earth. In Matt.19:4, it's about God specifically creating Adam and Even and declaring them to become one per Gen.2.
No, nothing vague at all about them. But what is vague is that from these four occurreces of 'tohuw' you somehow think that it indicates that, for some unfathomable reason, we have a creation in scripture that is not mentioned explicitly (that is, not vaguely) anywhere in the entire bible.
Already you're trying to assign the Scriptures I point out as having failed, before all the Biblical evidence is even in. Your last statement is irrational, since I've constantly declared that God emphatically created the heavens and the earth per Gen.1:1. It is explicit, and emphatic, in the Hebrew also.
Point really is, you cannot break what God showed with saying He did NOT create the earth 'tohuw' per Isaiah 45:18. And then with the earth in a tohuw state per Gen.1:2. There's only one simple and true Biblical solution to what He showed with that; it's that the earth became a waste and a ruin at Gen.1:2 because of some event. The simplicity of that Scripture comparison, is that if... one says God was creating the earth at Gen.1:2 in a tohuw ("without form") state, then it directly contradicts what He said in Isaiah 45:18 that He did not create it in that tohuw "without form" state.
So, the question is, did God create the earth in that tohuw state described in Gen.1:2, or not?
Doesn't matter how many other Scriptures you might try to bring into that in order to try and prove He did, because His declaration in Isaiah 45:18 is emphatic that He didn't. It's a simple matter of accepting that anything else other than what He said there is to contradict Him.
