Is this your belief, or the belief of scientists who try to figure things out like that meaning that is how you think or believe humans came about?
It's what the evidence tells us. If the fusion would have happened BEFORE the split with chimps, then chimps also would have only 46 chromosomes.
It's not rocket science.
Because if a person does believe that, or think it might be true, could it also be said that God had a hand in this?
Sure, it "could". Just like it "could" that pink undetectable genetic fairies worked their magic.
But there is no reason or evidence to suggest such. Meanwhile we have a lot of evidence of chromosome fusion in other species and we know for a fact that chromosome fusion is a genetic mutation that can occur.
It's like when chocolate cookies are missing from your kitchen. Your child's mouth is full of chocolate. His hands are full of chocolate. His t-shirt is full of chocolate. "could" it be that extra-dimensional aliens materialized in your kitchen and stole the cookies and then planted chocolate on your child to make it look as if he's the one that took them? Sure, it "could". But why would you consider that more likely then your child having taken and eaten the cookies?
This seriously is on par with your suggestion that "god might have dun it".
Especially since it is written, "Let us make man in our image." I've had to come to terms with the viewpoints, one -- is evolution the key factor in mankind's existence?
Evolution is the evidence based view. On par with your chocolate- stained child having eaten the missing cookies.
The (literal) bible claims are on par with the extra-dimensional aliens having stolen the cookies and planting false evidence on your child to make it look as if the child took the cookies.
Can you rule it out? No. But why would you favor that explanation over your the sensible one?
or does the Bible make a proper proclamation as to how life began and progressed on this earth?
No. Tales of magic are not proper "proclamations".
Just like tales of extra-dimensional chocolate cookie stealing aliens aren't.
Just like we "don't know" in case of the extra-dimensional aliens.
== that evolution does not have a mind to determine by mental capacity its own progress
The whole point of that demonstrable process, is that it doesn't need one.
, but by supposed mistakes (mutations as in the fusion process said to have happened) or survival of the fittest.
Mutation + competition over limited resources + natural selection, is all you need for evolution to work.
