many scientific facts have criticisms
Scientists appreciate criticisms and try to find and give an appropriate answer. Religious texts don't.
I guess the earth isn't round then, since flat earthers exist.
With scientific discoveries, it's
proved that earth is a sphere not round or flat. Religions are different than science and aren't proved yet to be true.
I guess no economic system is preferable, since they're all criticized by different people.
Again, you can't compare religion with economic systems. Economic systems are considered by how good they are, you can't do the same thing with religion.
If God wanted robots, He would've created robots who never choose or criticize anything. Instead, He created humanity to be His children.
Then, why does he want all of us to do what he says? I wouldn't do this to my children.
Hypothetically, if Christianity were true, the bible blatantly says that the way to God is narrow and few find it.
Sounds predetermined. So unfair, negative and elitist from this lawful god.
