Super simple question that I'm sorry for wasting peoples time with, but why is tjis piston extended when the redstone torch above it is unpowered? No other redstron is below or behind it...
It's called quasi-connectivity, pistons can be activated by redstone that would power the block above them, even if there is no block above them.
So it's the block with the redstone torch 2 blocks above the piston that's powering it.
An extra complication is that the piston needs a block update to "discover" that it's being powered that way.
So if you add redstone power diagonally above or 2 steps above a piston it won't extend until you, for instance, place a block or do something else next to it.

Thanks in advance!
because the block above the block above it is powered. see https://minecraft.gamepedia.com/Tutorials/Quasi-connectivity

Mumbo Jumbo has a bit about quasi-connectivity at 3:53 in his video on the differences between Java and Bedrock Minecraft.
