That was me. I always thought of myself as handy with cars though, not necessarily of heavenly origin. In fact, one person whose car I repaired with a leatherman and a coke can as my complete toolset and materials store thought I was a miracle worker. (I hope that fix held up until he got home...).
More seriously though, people who are that far into religion will see 'the hand of god' in just about every normal phenomenon, my paternal grandmother was one of those and she deeply believed all these things to be true, even when there were perfectly ordinary explanations for them. That never stopped us from getting along just fine, but I wouldn't press her on such items because her world was fragile enough as it was.
Religion is comfort food for the mind, and if someone needs their 'angels in human form' then maybe we should just let them.
Materialist or skeptical views are also comfort food for the mind, though. It's just comfort for a mind that's differently tuned.
These beliefs project a very basic, easily understood view of reality - discount vast amounts of difficult or inconvenient experiential data which has been with mankind since the beginning (ETs, visions, dreams, ghosts, the paranormal, faith healing, synchronicities, etc.) - and papers over a variety of huge and fundamental questions (origins, purpose, life after death, etc) with a very solid, tangible, and pat answer.
People who are deep into materialism will also see materialism everywhere, so the effect also happens that you mentioned with your grandmother.
Materialism is a theory in the philosophy of the mind. Its main competitors are idealism, dualism, and neutral monism, not "mysticism".
And, materialism has no more physical evidence than its competitors do. Whatever observations materialists claim as "evidence" for materialism, advocates of competing theories will say that those observations are just as compatible with their own theory as with materialism. If competing theories can explain these observations just as well as materialism can, then those observations turn out not to be evidence for materialism at all.
