My favorite arguments in this regard are megalithic structures like pyramids and religion. No matter how much Egyptologists prove that the pyramids were built only by primitive methods, I will never believe it because I myself worked as a builder for 10 years. Their arguments are that they found traces of primitive technologies, but if I flew to another planet in a small ship, I would use everything that comes to hand, including primitive workers. No one has yet recreated the ancient technologies of stone processing even with the help of modern tools, and this is a fact.Oooooh, again, great ideas! Although, some people say that alien civilization is behind in evolution, or equal to us in evolution. Is there any evidence that destroys that claim and helps support yours?
As for religion, the apocalypse predicted contactless payment methods, the number of the beast and global warming, which is described by Milankovitch cycles. In one of the apocryphal texts I also read about the ice age after that. The sun will burn people, and then the earth will become like chalk. They knew what would happen for a very long time. If people still consider them their god, then they are probably more developed) In general, when you do not listen to different sermons about aliens and you yourself study the primary sources and different facts, then everything becomes too obvious. Here, rather, the decisive factor is not the lack of evidence, but the unwillingness to face the harsh truth, sort of like finding out that Santa Claus does not exist
