uh, dust. "orbs" really are nothing more than just microscopic dust particles, water droplets, tricks of light through lens.... there are so many things to explain them that their credibility is virtually non-existent. Show me a full bodied apparition that can't be explained and then I'll believe.
Take a good look at the lighting on this photograph - can you see that the "orb" is reflecting the light that comes from above it? Would suggest that it's being created by a solid object. Plus the fact that it's been taken in what I presume is either early morning (I'm going by lighting again here folks, could be late evening) when there can be a lot of moisture in the air. So like it or not, I don't see anything even remotely credible in this picture..... but it is nice for you to have something to believe though
