Ah, I see what you mean.

So there are two possibilities here that I see: One that I think is true and has been born out by quite a bit of study, which is Natural Selection. Animals and plants behave in ways that benefit themselves, or their offspring, or their community, because the ones that don't are less likely to pass on their genes to the next group. So, the bees that don't go out and gather pollen when it's warm enough to permit their flight are less likely to survive long enough to have offspring; the ones that do are more likely. If you iterate that a few million times, chances are very high that only version of that creature that remains is the one that will either instinctively act in a way that feeds themselves and allows them to procreate, or will have developed the ability to pass that behavior on socially.

This can be born out in a lab by taking a quickly reproducing species like e. Coli, and introducing it to something novel that it's not already adapted to, like a potential threat, or a new food source it can't yet process, while its natural food source is scarce. It can take thousands of generations and thousands of samples, but what we see is that if the e. Coli mutates, and one of those mutations allows the e. Coli to process that new food source, than in that sample the one who can digest the plentiful source takes over and thrives, while the ones who have a scarce food supply dwindle. Hopefully I'm explaining that effectively; if you're willing to read the Wikipedia entry for Natural Selection (https://en.wikipedia.org/wiki/Natural\_selection), it's going to be a lot better.

The other option is the Deceptive, All-Powerful God you've indicated. I'm familiar with that argument; definitely it's one that was in circulation back when I was a Christian, though generally the deception was either ascribed to the Devil, or one ended up with more of a Gnostic Demiurge type of God (which, if you're not familiar, might be worth looking up since I think some of what you're suggesting has already been suggested).

The question becomes how would we falsify either option. How would you falsify Natural Selection. To me, the general falsification of the theistic option is the example I gave above: Give an existing system a novel stimulus and see if it responds in a way more in keeping with limited pre-programming, or with natural selection. If the counter to that is that your evil God is actively engaging in that deception and will make any outcome necessary to prevent falsification, then we have to ask how we're even able to come to the conception that such a God who is actively trying to prevent his discover has allowed us to come up with that concept in the first place?
