We all love to hear our own views repeated back to us. Religion is the ultimate form of echo chamber, not only do you pick a religion that fits your personal bigotries it's then further solidified by weekly teachings and social gatherings of similarly minded people. As someone with religion you also cut out those of other faiths or even kill people who disagree with you!
This is why I'm atheist before even getting to faith and belief. I don't think you even need to look at that aspect though it's hard to have a logical argument about faith as it's entirely based on faith and cannot be ratified. Logically you should have a religion to hedge your bets, but that's not a satisfactory reason either.
Most things a religion aims to provide you are advantages over others, like schools, jobs, deals etc just like business clubs the freemasons, secret societies or GLOs. There are tangible benefits to some, i fail to see any spiritual need for them though.
It's pointless arguing about the existence of god, it cannot be proved. And the emphasis should be on proving as even if you say things like god made man, that is just one of many things you could say, when explaining our us. That a science fiction writer like L. Ron Hubbard can create a new religion in our lifetimes should show you the fallacy of trust in religious writings.
We are circling around a 3rd or 4th generation sun 13.772 billion years since an event where matter was pure energy, this doesn't demonstrate a beginning but does suggest cycles that destroy everything we know to exist. We are literally made of stars. The entropy of everything is a far more powerful an idea than creating an unseen being just to explain away the creation of a few lifeforms.
