As a person of faith, I question that every day. I applaud all of the answers here, because the answer is that no one really knows. Each person should be free to believe as they see fit, including having no belief system at all.
I think the vast majority of people on the planet believe in some type of creator. A lot of Democrats have a deep faith, including Kamala Harris, Barack Obama and Joe Biden, so I'm always a little sad when people make negative comments about those of us who choose to believe (not necessary saying that is happening here), but it's for each of us, individually, to figure out and explore.
The one thing that I DO know is that when religion - ANY religion is forced on someone - the basic, human response is to resist. So no one should ever be forced to participate in religion or religious activities unless they choose to do so freely. That's why we have and we will always need separation of church and state. There's no gray area in that as far as I'm concerned.
Thanks for an interesting thread.
