Do you believe in magic?
Science fiction writer Arthur C. Clarke formulated:
When a distinguished but elderly scientist states that something is possible, he is almost certainly right.
When he states that something is impossible, he is very probably wrong.
The only way of discovering the limits of the possible is to venture a little way past them into the impossible.
Also, any sufficiently advanced technology is indistinguishable from magic.
This third one is most interesting, as it is often used to imply Christians believe in magic, and abandon science, where magic is another name for god.
Science is about evidence.
If there is no evidence there is no science.
There may be conjecture, theories yet to be disproved, or interesting possibilities. It is important to remember this as many who say they follow science, believe a thing to be true, but without evidence, it is just a faith.
So a competing idea to:
Any sufficiently advanced technology is indistinguishable from magic.
Any phenomena, outside of our current ability to detect and define, must be aliens.
In current culture, aliens abound.
Four hundred years ago, it was not aliens but devils.
