Remember that Earth is just One of Trillions (10^12) of Planets in the Milky Way Galaxy and just One of at least Septillions (10^24) of Planets in the Observable Universe...
In the Milky Way Galaxy are at least 500 billion stars, and every star has at least one planet, and the Milky Way Galaxy is just one of at least 500 billion galaxies in the Observable Universe
500 000 000 000 stars * 500 000 000 000 galaxies * at least one planet = 250 000 000 000 000 000 000 000 planets and Earth is just one of them, just one of 250 000 000 000 000 000 000 000 planets in the Observable Universe
OK, this everything is in the Observable Universe, and what is beyond?
How many are civilizations in the Milky Way Galaxy?
How many are civilizations in the Observable Universe?
How many are civilizations beyond the Observable Universe?
To know more we have to wait for:
James Webb Space Telescope (2018)
European Extremely Large Telescope (2022)
What do you think about this?
