The explanation that these constructions are deemed unlikely differs based on each one in particular, but at the same time, this is more than enough evidence that science no longer holds the secrets of all.

Many of the structures you see in the pictures below are all constructed in remote areas, rendering them difficult to create under standard circumstances.

Plus, they’re all so complicated in design and reliable that it’s extremely difficult to picture anyone performing this by hand.

In certain instances, you will also find constructions that are the size of literal mountains standing on top of a single pillar that would be difficult to construct even with the usage of today’s technologies.

You’d need millions of money, thousands of staff, and more time to produce something that’s as reliable as a regular human being in a lifetime.

.

Nobody knows the mechanisms used to build them, that’s for sure, but we have three hypotheses that we adopt.

First, we assume that the cultures of the past have had links to some methods and equipment that have been forgotten over time.

Second, there may be a hidden way to create this without utilizing too much money, one that we haven’t yet found.

Fourth, maybe this is another example of aliens offering humanity a helping hand. Irrespective of that, this is one puzzle that we haven’t yet solved, that’s for sure.
