we can kind of make an assumption that 00:04:22 complex brains and by extension complex intelligence should also be somewhat common in terms of evolutionary success and assuming that it's evolutionary preferential or basically that evolves many times throughout the history of the 00:04:35 planet we can then make a conjecture that it should exist somewhere out there where life exists on other planets okay just to rephrase this if we truly believe that extraterrestrial intelligence exists out there and that 00:04:48 it kind of evolved in the same way that it evolved here on planet earth it's pretty safe to assume that it might have evolved several times on the planet because we're making an assumption here that this is an evolutionary advantage 00:05:00 that all planets that potentially have life on them are going to end up with some kind of a species that's going to become super intelligent and that's going to be self-aware able to use technology and essentially kind of communicate in the same way that we 00:05:13 communicate using for example radio waves
