Recent events have shown that indeed UFOs are real. But what are they? Keep in mind all opinion is equally valid. I will go first. UFOs in my opinion are from different realities. They shift in and out of ours. I believe there are parelell Earth's. Each slightly different. The craft we see are from other realities. Other Earth's. They come here to observe and gather data. I believe UFOs are us. Just different us. Perhaps they want to test our capibilties this is why they been seen around nuke sites. And engage our planes. These craft also seem to know and understand our current tech. And have the ability to mimic them. This is why I believe UFOs are US. Just a different us.
