Your post just tells me that you haven't understood god's will at all and are simply angry at him. You don't need evidence to prove god. You need faith. You need to look away from your naturalistic, scientific, sinful methods and see through you heart. You must have faith and then you'll know god exists without needing any evidence to prove it. The analogy you have presented here is completely different. Those aliens did not create Bob. They did not love Bob or Alice. But God created you and loves you. You should stop being angry at him and accept his existence on faith just like he wants you to.
