This is confirmed by the existence of so-called extremophiles – organisms that thrive in conditions that are lethal for other forms of life. These conditions may include high pressures, presence of toxins, absence of oxygen, extreme temperatures and acidity. One extremophile species, the Ferroplasma acidiphilum, is a microorganism that can only survive in environments containing such large concentrations of iron that any other life form would expire there. Not only can extremophiles thrive in these conditions, but they cannot survive in what are considered to be normal environments. These organisms alone prove that life can exist in conditions on planets that were previously thought of as too extreme (Silverman, 2009).

Numerous UFO sighting reports can be considered as a strong piece of evidence in favor of the existence of extraterrestrial life. What makes some of these accounts difficult to deny even for the strongest skeptics are claims made by reputable people, such as law enforcement, the military, pilots, and even astronauts.
