What does god have to do with free will? Free will is an electrical signal sent from your brain that travels through neurons in your body to trigger muscle movment.
Perhaps god IS omnipotent, but he is certainly not involved in this part of the universe directly. RSG was right about religion not being forced on everyone, but he was wrong about claiming that jesus will return and "cleanse" the world of non-believers.
Unless there is at least a shred of evidence that jesus did resurect from the dead (other than a fictional book of fairy tales) then the argument that jesus IS god, has no foundation. Jesus could have existed easily, but to resurect from the dead is what divides belivers and non-believers. A tiny bit of evidence would help.
Even theories can not be called theories unless it can be tested. Creation is not even a theory. How can we test a claim that noah built an arc with no evidence? Or that god spoke to Abraham and orderd him to kill, with no evidence?
One can claim that life science is just biology, which is just physics and chemistry....etc etc and break everything in a reductionistic approch, down to the sub-atomic particle to explain that God controlls quarks and free floating electrons. At least science reduces claims to different forms of science. Religion does the opposite, building on one idea and exanding it to fit into every explanation of the universe with zero evidence.
So in honesty there could be a god, but no religion on this planet could explain who he is, or what he wants us to do. That is what science can allow everyone to figure out, rather than force that truth onto blind followers.
Next time someone tries to use science to explain why the bible is true, or that god exists, or that creationism is the truth. Please slap them in the face.
