Is believing in God the same as believing in Santa Claus?

I mean, think about it. There’s no evidence that either of them exist. The only difference is that Santa would be on earth and easily disprovable while God is supposedly a person up in the sky OR all around us. But how could God be all around us? You could argue that God is nature, but that’s only because it’s very hard to prove wrong and impossible to prove right.
Personally, I believe that religion is an excuse for the unexplained. Right now, I’m agnostic. A few weeks ago I was Christian. I have yet to read the Bible, but I have friends that are Christian who have debated with me on things like this. (Friendly debate). I have a feeling if I ever become Atheist that I’d do a conversion to Christianity on my death bed just cause it’s a sad fate when you believe there is no God or heaven. Just blackness. Also I feel like it’s an unaccepted/bad thing to believe or disbelieve however you look at it. But I do think Atheists are probably the most reasonable.

Alright so I have 2 questions up for debate:
1. Is believing in God the same as believing in Santa as a kid?
2. If you are Atheist, do you think you’d make the conversion on your death bed?
OR if you are Christian or any other religion that believes in God, why do you believe in God and is there any evidence that he exists?

***Disclaimer: I’m aware that this is a controversial topic and I’m not asking anyone to change their beliefs & I accept all religions. I am not trolling because I’m not looking to piss anyone off, just making a point. I will not get amused from causing controversy.***
