You are simply not even acknowledging, let alone addressing, the weird patterns that have tied the most far-reaching human breakthroughs in social altruism with the most counter-cultural and nose-tweaking takes on deity. Of course, bats and plenty of mammals have ingrained altruistic habits as well. But we don't (yet) know fully the feelings other mammals feel or the thoughts other mammals think. We do, though, know something of the cultural habits that humans adopt. So humans are our best laboratory for determining what goes into the gestation of altruistic behavior through different civilizations through different millennia. That is the laboratory that has helped reveal this odd quirk that always ties new "altruisms" to new "theisms".
Of course, anyone has a right to come up with some explanation for this pattern that does not upset the assumption that there's no deity. But it's absurd to actually pretend the pattern doesn't exist! What's the point of your OP if you don't address any of the reasons submitted why there MIGHT be a deity?
If there really is no deity, then fine, explain this pattern some other way. But explain it! Don't just pretend the pattern doesn't exist.

While you have not offered much if anything in the way of evidence to support your claim.that "the most far-reaching human breakthroughs in social altruism [are tied] with the most counter-cultural takes on deity", Slowvehicle and others have offered substantive rebuttals to that assertion.
Even if you had, or could, offer more significant support for the idea, the conclusion that altruistic social engineers have largely been believers in a god or gods still does not give me any reason to believe in a superpowered invisible overlord of the kind that the various monotheistic world religions
hold in high regard.
