Pyramid-Shaped UFO. What if...?

You know the "Great Pyramid" in Egypt is the only one there that is unfinished. In case you were unaware, there is a lot of controversy concerning who built the "Great Pyramid", how it was built, and the fact that it is the only Pyramid in the vicinity that is missing it's capstone.

"Capstone" is also a "cornerstone" in the case of the "Great Pyramid". This curiously correlates with an interesting passage in Psalm 118:22

"The stone which the builders rejected has become the chief cornerstone."

Jesus quoted this verse as recorded in Matthew 21:42, Mark 12:10, and Luke 29:17. In each of these accounts, Psalm 118:22 was clearly quoted in correlation with Israel's rejection of Jesus as the Messiah. In other words, Jesus identified Himself as being the "chief cornerstone ". This is further confirmed in Acts 4:11 and 1st Peter 2:6-7.

What if (and believe me this is a BIG "what if") one of these pyramid-shaped UFOs that the Pentagon has confirmed lowered onto the "Great Pyramid" and fit perfectly as the capstone?

Could that be part of the "strong delusion, that they should believe the lie" as written in 2nd Thessalonians 2:11?
