It’s pretty unlikely, but even if there is/was a God/god/s, he/she/it is probably not what we have imagined. If God (whatever that means) exists like the typical version of The Christian God (whatever that means, since even the Christians can’t seem to agree) then why in the world would that God give so many other people (that far outnumber Christians on earth) a completely different faith or vision or idea of what “God” is like or what kinds of rules he’s set up? And why would he make sure that everybody’s beliefs in their own particular brand of faith are exclusionary to everybody else’s and mutually exclusive (we’re right, so you’re wrong and if you’re wrong, you’re going to hell)?
Just because we exist (or think we exist) doesn’t say anything about the origins of the universe or the earth or of human beings. It just presents more questions for us to try to figure out, if we want to, or not, if we don’t feel the need to understand how it all started (or didn’t start, but always was). Humans tend to have a need to understand how we got here, or what we’re here for. But some of us would rather spend our time on just trying to get along well enough with the people and resources that are here so we don’t end up getting killed (at worst) or treated poorly (which is still very common).
If it helps people to sleep better at night, and they don’t use their own brand of faith to make laws that negatively effect others, or use their beliefs to simply treat others poorly (because they’re not worthy due to their supposed lack of faith in the correct God) then it’s perfectly fine for them to believe and follow whatever doctrine they want. Unfortunately, if you look around the world today and for thousands of years into our past, you can see that faith in this or that religion, has caused (along with greed) most of the wars that have been waged. Wars, waged in the name of something that no one even knows if it exists. And that is the way it will probably continue to be well into the future.
So I’m still going with, not very likely.
