But what caused the chemicals for life to even exist? Nothing makes sense, it goes on forever. Even those dead set on a religion, sure God may have created to universe, but how did God even come about? He can't just all of a sudden exist can he? But it also makes no sense for things not to exist either.

Those chemicals exist as product of the creation of the planet. That goes back to the formation of the planet 4.5 billion years ago.
The religious people play an intellectually bankrupt game where everything must have a cause, except their god. It's how they get around holding their God to the same standards and reasoning that they hold everything else to. I don't buy any of that.
If you're talking about the universe, nobody knows what came before our expanding universe, or even if there was a "before", since time itself is a product of our universe and its unique rules. Maybe it's an endless cycle of expanding and contacting. Or maybe it's something else entirely. Quantum physists are pretty sure we are in one of many universes, each with its own rules. It's an interesting question, but not one we have a definitive answer to, yet.
Do you believe that everything that begins to exist has a cause?
