Lets compile a list of everything wrong with christ-insanity

[DeistPaladin]

I don't think a deist god would considers us insignificant.

It's a matter of scale. In the universe, we are as individuals insignificant. My sense of meaning in life is how human civilization will continue after I'm gone. Perhaps God is watching us, perhaps having countless frames of reference while we as humans are limited to one, but I see no reason to think so. I guess I just don't speculate on the nature of God too much beyond "mysterious mind behind the universe".

If he exists, so does heaven, right?

Not necessarily. Many deists reject the idea of an afterlife. The rest "hope" for one but have no idea what that would be. I personally lack a belief in an afterlife. We just don't know. I'm content that God gives us one shot at the brass ring and then it's fade-to-black, roll credits.

Interestingly, my wife is an atheist who believes in an afterlife. This underscores how the existence of God and the existence of an afterlife are two separate issues. There's a quadrant of possibilities:

1. God exists. The afterlife does not. (See OT Judaism)
2. God exists and so does the afterlife. (Islamo-Christianity)
3. God does not exist but the afterlife does. (Buddhism)
4. God does not exist and neither does the afterlife. (position of many atheists)

Just because there is a god doesn't mean we're important enough to preserve. Just because there is no god doesn't mean there isn't some natural mechanic of consciousness that survives the death of the brain.

What if we are just some experiment?

Perhaps we're proverbial chips off the proverbial block? We as humans need to create. It's just in our nature. And we need these creations to be bigger than ourselves, ones that can be independent of us and have a life of their own. Maybe God is like that?

Oh well, at least there's no hell.

I would agree that's the least likely scenario.
