"Why not a proof/Sign/indication" - challenge and various responses to it in Quran.

[Aoi Magi]

No Atlas, see there is a very big difference between the "ancient aliens" community and the actual scientist community. Archaeologists while encountering a past monument might not always know how it was made, and they will claim that they don't know. Then they'll present their hypothesis on how it might have been built and move on to finding proof for their hypothesis. On the other hand, a person from the AA community simply points to that gap in knowledge and claims "aliens did it". There is no attempt to form an actual hypothesis and/or back it up with evidence.

Also, regarding your or any other holy scriptures, they are written by humans claiming to be inspired by god. There is no reason to believe that claim if you don't trust humans. And in reality you shouldn't trust humans, rather you should base your trust upon evidence that can be verified and re-verified as needed.

The ancient astronaut theory is acknowledged to be "pseudoscience"; but evidence showed that many theories and stuff accepted to be "facts" by the scientific community, turned to be pseudoscience in the end.

Einstein and the static universe he believed in is my example.
Personally; I would treat a scientific opinion with more of a relief than pseudoscience. But just like the static universe; and just like the majority that "never looked back because the father of the atomic bomb believed in the theory", I must say that any scientific opinion could prove to be pseudoscience in the right time.

I trust my feelings; though. The idea of God in the Quran, and the concept of giving in to become a part of the universe is just astonishing for me.

That example of "static universe" is a good example of why the scientific method and peer review works a lot better than gut feeling. See, if Einstein just followed his own opinion/feeling about it he'd have stuck with that idea, which would have been wrong in the face of reality, but because of Huble's findings did not match with his, he corrected himself and proposed other models. Science works because it keeps correcting itself to get closer to the truth, personal feelings not so much.
