Why does it follow that if there is a God, His existence should impinge on mine, or that I should worship him?
The importance of the existance of God is two-fold.
One, He is not a natural being, He's supernatural. Therefore, if God exists, so does the supernatural. And if the suerpnatural exists, then there is a basis for all of these life-after-death claims we theists make.
Second, God not only built this place, but created all the rules that govern it. Therefore, you (which includes the supernatural part of you) are goverened by those rules. This is where all this heaven and hell stuff comes from. The rules that govern this place will put your supernatural self into one of those two locations. Which one is up to you.
The "why you should worship Him" part makes sense once get to know Him. In short, worshipping God is a god-sized take on honoring your parents. It's a way of thanking Him for all He has done for you.
