Question

evidence that extraterrestrial life exists in the universe is made stronger by all 1 point of these except
○ extremophile organisms found on earth
○ documentaries and social media posts about aliens
○ the shear size of the known universe and the planets and stars that exist

life that exists other than that on earth 1 point
○ big bang theory
○ extraterrestrial life
○ asteroid belt
○ extrasolar planet

Explanation:

First Question (Evidence for extraterrestrial life except...):

To determine which option does not strengthen the evidence for extraterrestrial life:

• Extremophiles on Earth show life can exist in harsh conditions, supporting the idea that life could exist elsewhere.
• Documentaries and social media posts about aliens are not scientific evidence; they are media content, so they don't strengthen the scientific case for extraterrestrial life.
• The size of the universe and number of celestial bodies increase the probability of life existing elsewhere (more places for life to potentially form).

• Big Bang Theory explains the origin of the universe, not extraterrestrial life.
• Extraterrestrial Life is defined as life existing outside Earth.
• Asteroid Belt is a region of space with asteroids, not related to defining life outside Earth.
• Extrasolar planet is a planet outside our solar system, not a definition of life.

Answer:

B. Documentaries and social media posts about aliens

Second Question (Life other than on Earth):
