As the others are saying its probably a bird. Even if it isn't I haven't the foggiest idea where someone would get the idea that its a spirit.
Honestly in this day and age why would you think a bright object in the sky is a spirit-orb? That's like seeing something moving in your bushes and
assuming its a Leprechaun.
I watched the video and that doesnt look like an orb to me either..its a bird in flight you can tell by just looking at it..But a nice video of the
wall...
