In other words, there is no logical basis for accepting one as true and the other as false. You can't point at a Bible verse which states it is the word of God and use that as your proof, because you have to assume that the verse is wrong. I can say in my Bible that it is the word of God, but that doesn't make it true as well. To my knowledge, no one has ever disproved that I can walk through walls, or that Bill Gates is a Martian. The fact that no one has done so is not a compelling reason to believe that I can walk through walls or Bill Gates isn't human.
Facts have to be proven to be of any value.
To believe everything that hasn't been disproved is totally absurd. I agree that God has given the laws in our hearts. We have the ability to look at our world, refrain from doing things that harm others and not worry about those who find happiness in ways different from our own. The laws we have but don't obey are to treat everybody with the utmost respect, with honesty and with compassion, and to not take more from others than what we give out. The Bible does not teach respect and love for all people.
