scientific knowledge confirms that life does not arise from non living material
This is completely wrong. Scientific knowledge has confirmed that the mechanism of life is quite ordinary, and that the kinds of chemistry involved can arise in naturally occurring circumstances. We can dissect the machine, see the working parts, and confirm that the machine quits working when the physical, material parts are disrupted. Simply moving the material apart a couple inches turns it from living to non-living. Same stuff, just not stuck together right. No invisible parts required.
The bible says that 'with God is the source of life' It acknowledges a lifemaker... it says that he created life on earth. So yes, there was a time when there was no life on earth, then God created it.
Then we are agreed. Abiogenesis took place on earth. If I claimed that 7 gods were required to cause it, would you accept that? I think not. Why not? Because your claim explains it without the need for 6 of those gods. Well here's a news flash: Since we understand the chemistry that defines life, and have plausible explanations for how it might have arisen through the natural behavior of the stuff from which the universe is made, god #7 isn't required either.
To paraphrase a old standby: If you can understand why life doesn't need 6 extra gods, you should be able to understand why it doesn't need any.
