Biological Mechanical Extraterrestrial Beings or BMEB's is my hypothesis proposing that extraterrestrial life has evolved from biological to mechanical beings. While the hypothesis is not new, the name is and its why I say "MY" hypothesis. 

The hypothesis suggests that technological advancements, such as prosthetics and artificial organs, led to a completely mechanical body. This challenges our traditional perception of extraterrestrial life and directs our search towards machines instead of biological entities.
