ALIEN CHASES MAN Caught on Tape

This video allegedly shows an instance in which an alien was caught on tape chasing a man. The video itself was taken in the Northwestern United States and was sent to us by a man who has claimed to have several sightings of these alien creatures, however this is the first time in which he has caught one of these creatures on tape. He saw the alien prior to recording and once he began to record, the alien began running towards him. Does this footage really show an alien sighting caught on tape? What do you
