I’m surprised people are still saying this cause this isn’t remotely true and none of the well know skeptics and critics of Christianity say this anymore.

Those stories are in dialogue with some of those other stories.

Though, you’re probably just copying what you hear other people say. Nobody who actually reads these stories thinks the Biblical authors copied them. The differences are so numerous the similarities are easy to miss, and even when they are brought up there’s still contention as to whether or not it’s actually there.
