Orbs, I believe have at least dual roles in bringing and being alternate life forms that reside in the unseen world around us. If this highly energized ionzed gas or plasma or whatever constitutes it's makeup can be conscious of us and behave in a way that shows some crude reactionary expression then we are looking at a very transferable life form that doesn't need to be of any density similiar to our makeup. Something that is chameleon like and in my opinion probably very common throughout our solar system, Galaxy and even more complex throughout the universe.
What I witnessed was not just some mindless Orb with no purpose or intention.It clearly noticed me standing still 30 feet away with camera in hand and wanted or perhaps curious to meet me up close.What took place after I watched it approach me through the air is still hard to grasp and I can understand how it would be diificult to believe. If I didn't take that digital still I might have even doubted myself because it truly was extraordinary.I'm leaving out so many other details because this encounter is not something you can condense in a online forum. I guess I did have a close encounter of some other kind just what it was exactly with many other questions still linger.
