Why should anyone even want a relationship with God?

[Welsh cake]

For me, if there really is a god out there, then it seems like I have no choice but to accept it as my Creator.

If such a being exists, why call it "creator" when it didn't directly and intentionally create you? We came from our parents, and they came from theirs. We're the current state of an unbroken chain of life going back to single-celled organisms/viruses. Were it broken by chance, by ill-fate, by circumstance, we would not exist.

You need to exercise a little more critical thinking. We're just biological, physical and chemical arrangements, temporary sequences, we're not "creations" of anything eternal such as a deity (whatever deity means). We're lifeforms. Life is merely a process. Life may arise from non-life, and with certainty, revert back to non-life again with death.

Hypothetically, if they weren't though, I think that in itself (i.e. the fact that it's truth) is enough reason to worship that particular god, because I value truth and there's nothing that can be done to change the fact that it wants its ass kissed.

Currently no one has any good reason to think there's a god, let alone worship it. More-so what makes you think such a higher life-form with an indefinite lifespan, would want, need or care for your insignificant devotion?

When you get your hands on new technology, are you grateful for the sales person at the store or the innovators of the technology?

Depends. Are you grateful for the people who work in the national grid that ensure your home is provided with a near-constant supply of electricity to power the electronic devices? Are they grateful for you using their services and contributing to their salary/payroll because you HAD to buy the technology rather than suffer without?

Or are you realizing its senseless to be "grateful" in the context you're using because you HAD TO PAY to use the new technology, additional tax slapped on top by the heads of state, and for the weekly electricity meter?

Why do you feel like you owe somebody something all the time? That's not a healthy lifestyle.
