The signs are subtle and mysterious but there is no doubt that extra-terrestrial life forms are among us.
You have to be astute to see them and insightful to be able to interpret them. They are here and are trying to communicate with us.
Some people dismiss the possibility of aliens. Have you ever seen an actual UFO or decent photo of one? Even the US military with super high tech cameras and detailed high resolution satellites has only captured fuzzy, grainy images, but has admitted something is out there.
They are looking in the wrong place. They should be looking here on the ground where the signs are all around us.
