I'm like many of the others. I believe there are things we don't yet have the capacity to explain. Things that could be very real that are written off as something supernatural just because we don't have the reason for it yet... or the ability to comprehend it (woo string theory).
I was actually part of a ghost hunting group about a decade ago. Most of the time it was just sort of a fun activity for me that involved exploring old, creepy places, with a group of people who got us permission to be there. Sah-weet!
But we actually had one case where a professor of a university called us in to help a family. Shit happened that night that I cannot explain. Shit that makes me uncomfortable to this day. Does it mean I'm fully on the "oh yeah the paranormal is totes real" train? No. But it does mean I definitely think there are things we don't yet have the capacity to understand, but we also cannot deny. So for the time being, yes, some might call it supernatural.
Like, OK. I mean, it's not a supernatural thing... But people didn't know whether or not a horse's hooves fully (all 4) left the ground during a gallop until we had photography (https://en.wikipedia.org/wiki/Eadweard_Muybridge). The human eye couldn't track it, so it was apparently a big point of debate at the time. Then a photographer comes along, manages to get some photos, and proves: yes, during a gallop, there are stages where all four hooves are off the ground.
So what we call supernatural may just be something we don't have the capacity to explain with science. Which, again, puts me with the others above in their reference to the caveat. I don't blindly believe in the supernatural, but I think there are things we place under that umbrella until we can explain them properly.
