How do I get my mom to stop believing these conspiracy theories she sees online and on YouTube?

She's been really annoying our family recently telling us that "Our planet is a disc within a dome" and "Dinosaurs never existed", "the moon landing was fake", "Space doesn't exist", "all of the bad people are demons from hell", and more.

I'm just so sick of it. Any time I try to prove her wrong, she just ignores the statement or just says "nope your wrong" without giving any actual proof that I'm wrong.

I once asked her "if the Earth is a disc, how come I can't see the Eiffel Tower from here?" and she straight up said something about a real life render distance.

If I can't prove her wrong how do I just get her to stop believing everything she sees on the internet?
