They don't match with atheistic opinions.
There's no such thing as "atheistic opinions".
But they match very well with everything that can really be seen in real life.
As said already, these bible myths don't match the evidence of reality.
These myths make claims of real world events that would have been very impactful.
Such events leave behind evidence. These claims thus make testable predictions about what we should and shouldn't find in the real world, if these stories are accurate.
And when we investigate these predictions.... the evidence we should be finding doesn't exist.
And the evidence we should NOT be finding, does exist.
This disproves those stories.
Fun factoid btw: did you know that geology as a field in science was actually kickstarted by a couple of christians who set out into the world to find physical evidence of the magical flood claimed in the bible? As said, the story makes predictions about what we should and shouldn't find in terms of physical evidence. So these people went out looking for exactly that evidence. Instead of finding that evidence, they discovered that the whole thing is BS, and their work kickstarted geology as a scientific field in the process. So really.............. it's been KNOWN that this flood myth is false since pretty much the
start of geology as a scientific field.
I'm amazed at the amount of people who still haven't caught up with that....
