Extraterrestrial Life
The universe holds an enormous number of planets having conditions capable of supporting life. It’s mathematically more probable that some actually do have life than it is that humanity is the only one. Such life may or may not resemble us.
Here on Earth, life proliferates from the deepest depths of the oceans to the highest mountain peaks; from the icy poles to the hottest, dryest deserts. There’s life everywhere. However, high probability does not equal certainty, but its close.
