After watching a couple of videos ( pro and con ) for the Kalam Cosmological Argument, I see no problem with the possibility that the universe ( our spacetime realm ) may have been created and that therefore there may be a universe creator. The problem I have with it is when people make the leap from that to, universe creator = God. Gods are things that have been arbitrarily assigned religious significance by religious minded people, nothing more. Or simply put, Gods are things ( entities, beings, objects, whatever ) that have been deified. No deification = no God. Therefore with respect to the question of universe creation, the real question isn't, "Is there a God?", it's, "Is there a universe creator?" In other words, it's entirely possible to believe that there is a universe creator without deifying it and creating a whole hierarchy of religious rights and ceremonies that involve kneeling and worshiping and praying to it like a bunch of backwoods jungle cargo cultists.
The ability to create a universe is purely an issue of power, and even most religious people recognize that power ≠ goodness, and most people who choose to worship some God or another do so because they believe God to be good. That is a reasonable position to take if one feels the need to kneel before some supernatural entity, but there are also those who do it out of fear because they believe their God is so powerful that they will be punished for insubordination and relegated to some horrifying afterlife.
But I ask, is a God who rules by such fear worthy of true devotion? I don't think so. Demanding obedience under threat of everlasting torture is pure evil, and I'd sooner curse such a God from the depths of Hell than pledge my allegiance to such a morally corrupt deity. So when it comes right down to it, if one feels compelled for some reason to seek out some deity to kneel and pray and offer up sacrifices of time and money or whatever else is expected, then it seems that we have the choice to choose which God on the menu fits the criteria we believe our God should emulate.
So how do we know which God is better than the next? The Christian church laid claim to the one that came from the heavens ( sky ) and decided to play favorites in ancient Middle Eastern tribal warfare. And apparently, if we include all the cultures and Gods that have ever been documented, there are thousands more to pick from. So my advice is that if one feels it's really necessary to suspend one's disbelief for, and pledge one's allegiance ( and whatever else is required ) to, any one of these mythological deities ( or their alleged representatives ), then one should be really certain that the deity they are choosing measures up.
Make a checklist of all the attributes that you think your God should possess, and then do some comparison based shopping before writing the cheque. After all, we do the same thing when buying a house or a car or choosing a school, so why settle for a second or third rate deity? And don't be fooled. Every religion claims their religion is better than the other guy's religion. But take some time to look under the hood. You never know where some of these religions have been. The big brand names have a rather bloody and unsavory past despite what the guy on your TV seems to be selling.
