We know there are a few on this forum who think they are, but consider this for a while. If you are God, you are omniscient, therefore you have nothing to learn. Nothing to research, investigate or explore as there is nothing you don’t already know. No point exercising your skills against the ultimate chess master in the universe because you already know every possible move and outcome.
You are also omnipotent, so nothing you can’t do, nothing challenges you. You can build a universe as easily as clicking your fingers (or whatever you have for fingers).
You are also infinite. You had no beginning and will have no end. Before you created your first companion (Jesus if you like) you had already existed an infinite number of years all on your own. We’re not talking about zillions of years here, but a period infinitely longer than that. Zillions to the power zillions to the power zillions of millennia is still not even a nano-second when laid alongside infinity. Endless time with no one to talk to, no one to associate with, no sycophants to bow down before, no one to tell you how great you are, and of course, no one to slaughter.
How do you fill an infinite number of years being all knowing, all powerful and all alone? And when you do create someone, unless you create them equally omniscient, you will be infinitely cleverer than them. So Einstein with imbeciles for peers will be nothing compared to you and your peers. And if you’ve already lived an infinity of years without company, why start?
