Maybe they're not "ETs"

I got through most of this article. Some good points but I think there may be many situations going on. We may have space visitors, inter dimensional beings and advanced earth humanoids all here. Then there is the spiritual realms (if one is a believer). It’s all very mind blowing.
 
... on the other hand, maybe it's not true that one cannot exceed the speed of light or that the other planets in our solar system are uninhabited or that the only way of getting around in this universe is via physical travel.
