So, it seems that you’re an amateur and apparently not very well informed.
I’d really advise looking into scholarly works on the interpretation ideally written by people who can read Hebrew.
The obvious problems are:
Genesis 1 was probably written during the Babylonian exile
Even if it was written by Moses, if there was an Exodus of any sort it was almost certainly a much smaller affair - small enough to be invisible to history and archaeology. You can forget about 2 million former slaves.
The context for the writing doesn’t seem to match what you have in mind.
As a further caution trying to understand a work by picking out meanings for individual words without taking the context into account is an error. I don’t see any reason to translate “b'reshiyth” from the start of Genesis as “first fruits” - and you don’t make much of an argument for it.
