A UFO expert claims to have found a 'tomb entrance' on Mars

Scott C Waring claims to have found a tiny doorway that has been used by eight-inch tall aliens and is convinced that it is proof that extraterrestrials "once lived" on the red planet.

Waring shared footage of his findings on his YouTube channel and likened it to the 12-inch entrance to Ramesses' tomb in ancient Egypt.

He said: "This doorway is about two times the size of the people I have reported finding on Mars... 8 to 12 inches tall.

"With so much concrete evidence I don't know how archaeologists could deny such things.

"Mars is proof of life so early it goes beyond anything the Earth has to offer. 100 per cent proof that ancient intelligent species once lived and thrived on Mars."
