there is no direct evidence to confirm the existence of extraterrestrial civilizations or intelligent life elsewhere in the universe. However, the vastness of the cosmos and the discovery of numerous exoplanets (planets outside our solar system) have led scientists to believe that it is indeed possible, if not probable, that life may exist elsewhere.
The observable universe is vast, containing billions of galaxies, each with billions or even trillions of stars. The discovery of exoplanets has shown that planets are common in our galaxy alone. Among the billions of planets out there, some are likely to be located in the habitable zones of their stars, where conditions might be suitable for liquid water to exist – a crucial ingredient for life as we know it.
Given these findings, scientists believe that the conditions for life could be widespread throughout the universe. However, until we find direct evidence of extraterrestrial life or contact with another civilization, it remains a matter of speculation and scientific exploration.
The search for extraterrestrial intelligence, often referred to as SETI, continues, with radio telescopes scanning the skies for any potential signals that might indicate intelligent life elsewhere. But as of now, we can only consider the possibility and not the confirmation of the existence of humans or intelligent life beyond Earth.
