Many believe that it makes no sense to send out signals to search for ET life because of the idea that their existence started millions of years ahead of humanity, which makes them advanced enough to monitor Earth thousands of years. The idea believes that aliens saw bonfires set by ancient Egyptians and other Earthly activities around that time.
Astronomer Frank Drake is one of those people who are against sending out signals to search for extraterrestrial life because, for them, it makes no sense at all.
Drake was behind the first modern hunt for ET life in the 1960s and also the Drake equation, which quantifies the number of civilisations in Milky Way based on probability.
Currently, researchers at the Search for Extraterrestrial Intelligence (SETI) are listening out radio signals rather than sending them to potentially habitable planets. The search for intelligent alien life has received mix reactions with some saying that mankind might end up coming across an alien race that can do more harm than good.
Drake, 84, stated in a recent interview that he is against sending out signals not because of fear that evil aliens might know about mankind and when they do, they will come and invade our planet. Drake explains that he is against sending out signals because aliens have known humanity more than we know ourselves. So, sending out messages to let them know our existence makes no sense, according to Drake.
Drake said that aliens want mankind to be aware of their existence, so the efforts of listening to signals are more reasonable than sending out messages. He explained that aliens are doing us a favour to communicate with them, and it is up for humanity to listen what they want to tell us.
