O.k., and again I ask... if not the God of Abraham as described in The Torah, who?

Which God do you worship?
Your argument is specious.
The basis of your argument asserts that there is one God. YOU then depart from the premise, to claim there are three Gods.
The argument is invalid.
So you've two choices.
You can shut down this thread and start another one which asks, 'to which of the three perspectives of God should you adhere'?
Or you can continue to embarrass yourself by pushing this foolishness.
The evidence provides, to this point, that there is only one Creator. Only one intelligence which set froth the laws that provided for the universe in which we exist.
Worship that God, don't worship it. It matters to no one but you and God.
All the question amounts to is should you recognize that you're not God, that you owe your life to that which IS God and humble yourself for the opportunity which God has provided, or be a douche and reject God his gift and your own best interests in so doing.
Nothing complicated in any of this.
Looks like you missed his point. Read the OP again.
I did read the OP.
Then I read the post to which I responded, wherein the author changed the point of the OP.
The OP is clearly shifting the argument, because of the fatally flawed construct of his argument which is getting creamed, as is usually the case in arguments crafted by the Anti-theist.
God is what he is. Know one on this planet knows what he is, we each must consider what we know and reason from those set of observations, what serves reason.
But at the end of the day, our perspective is so small and low that we've very little means of ever truly understanding God. The good news there being that we have more than enough to recognize that whoever or whatever God is, we're not him. We know, given that we have no means to create ourselves, that owe our very existence to him, thus it follows that the least we can do is to use the gifts he has provided toward the fulfillment of our lives, which reason suggests is the reason we're here.
The denial of God is little more than the time tested argument: "You're not the boss of me". Usually advanced by those, of whom we are the boss. vis a vis, our children or younger siblings.
It never fails to tickle me when I run across these forums, that those who profess to be founded in "SCIENCE!" and "LOGIC!", claiming adherents to the physical laws of the universe, eschew to the depths of their worth, the laws of nature governing human behavior, as if they're any more debatable then the laws of physics.
Meaning that the same people who would never argue the existence of gravity and electro-magnetism, are absolutely certain that the laws against eating shellfish were CRAZY! And that the laws against promiscuous sex are NUTS! With similar views on the laws against theft, deceit, disrespect of one's parents, etc.... further rejecting laws which require high discipline against greed, lust, anger, sloth, envy, pride and gluttony.
Now the hilarity comes into play, where those keeping score recognize those 'sinful' traits, as the weaker traits of humanity, which are also the key selling points of socialism and it's wholly owned subsidiary: Anti-theism.
