>> If a being appears in the form of an apparition, could it be that they tele-ported or projected a vision of them to the material world? Maybe ETs or aliens are sophisticated enough to do this, at the moment quantum teleporting in our technology is already proven, what if they can do more than this?

And I disagree with what you said that G-d is not part of the material world, what about the part that G-d created the heaven and earth, and that he walked with Adam and Eve in the garden of Eden, and most specifically that Jesus, the son of G-d, was born out of a virgin, in flesh and blood, and lived and died as man and was then resurrected in physical form (new body) and went to Heaven? Isn’t that part of the material world?

Will the existence of a divine being such as the Judeo-Christian G-d really have to be an either or with the existence of other humanoid beings living on other planets?

I guess now that there’s a lot more people having access to information easily via the Internet, some hypothesis and theories are getting more popular these days, and one of them is the ancient alien theories.

There are more people now that theorizes that aliens might have helped them. It is not yet certain how these theories will stand on the test of time, but at the moment nobody knows for sure if aliens did visit the earth and co-mingled with the civilization back then. There are ancient texts from various ancient cultures, including the Bible, that clearly talks about extra-terrestrial beings or supernatural beings that have had contact with them before and taught them things. However, there’s not much incident like that now, maybe there are ET sightings, abductions or whatever, but most of them are speculations or hard to prove events that may or may not be true based on the evidence or testimony, and even if people write about it, I doubt that people will regard them now as historical fact, compared to what the ancient wrote before.

This is true for supernatural incidents as well. Take for example the miracles, apparition, sightings that are reported every now and then. That is why, I don’t follow the author’s logic that the alien and the divine or supernatural theory are different, they may be apples and oranges but they are still the same, they are fruits!

So much as the ancient or current alien theories must have factual or scientific evidence to be believable, so does the ancient or current divine/supernatural theory might as well have. At the end of the day, they are just both theories, it just happens that the ancient supernal/divine theories (in the form of religion) have more devout followers that have been believing that theory for hundreds or even thousands of years.
