their lifetimes are too short
Planets located in the habitable zone of their star (where liquid water can exist), planets with rocky compositions, planets orbiting stable stars, and planets with atmospheres that could support life would be the best candidates to search for extraterrestrial life.
Mars and Europa both have evidence of liquid water, which is essential for life as we know it. Water is a critical factor in supporting life because it provides a medium for chemical reactions necessary for living organisms. This similarity to Earth makes them potential candidates to support extraterrestrial life.
A lot of people, mostly scientists, claim to have proof of extraterrestrial life. They feel their theories are plausible. However, the subject of extraterrestrial life is debatable. There is no official proof.

Xenobiology is the speculative Biology of extraterrestrial life forms.
There are several reasons to believe in the existence of extraterrestrial life. One reason is the vastness of the universe, with billions of galaxies and planets that could potentially support life. Additionally, the discovery of extremophiles on Earth, organisms that can survive in extreme conditions, suggests that life could exist in harsh environments elsewhere in the universe. Finally, ongoing scientific research, such as the discovery of exoplanets in the habitable zone of their stars, provides further evidence that extraterrestrial life may exist.
Both Mars and Europa have evidence of liquid water, which is essential for life as we know it. Additionally, they both have the potential for organic molecules to exist, providing a possible building block for life. These similarities with Earth make them viable candidates to support extraterrestrial life.
