This summer while doing research on bigfoots, I ram across 3 different alenis thru out the summer. I've been going to the same place

I am a bigfooter, been going to the same place in the rocky mountains for 8 years doing research on the Bigfoot type creatures, this summer extraterrestrial type alein looking creatures have shown up, I've photograph them 3 times this summer. They were not there the previous 8 years. And I am confused as to why there hiding in the woods where I've documented 13 different bigfoots, and 2 yeti type creatures. I am lost there more aggressive then the Bigfoots. Any help would be great.
