Question

according to the video alien contact our best place to find extraterrestrial life in our solar system is
europa
titan
earth
mars
evidence that extraterrestrial life exists in the universe is made stronger by all of these except
extremophile microbes that eat rock
wow signal
crop circles and peruvian lines
the shear size of the known universe

Explanation:

First Question:

To determine the best place to find extraterrestrial life in our solar system according to the video "Alien Contact", we analyze the options. Europa has a subsurface ocean, Titan has organic compounds, Mars has had water, but Earth is where life is known to exist (and the question's context from the video likely aligns with Earth as the best - known place with life, even if looking for extraterrestrial, Earth's life is a reference).

We need to find which option does not strengthen the evidence for extraterrestrial life. Extremophile microbes show life can exist in harsh conditions (supporting extraterrestrial possibility), the Wow signal is a potential alien signal, the size of the universe makes the odds of life higher. Crop circles and Peruvian lines are more likely human - made or geological, not evidence for extraterrestrial life.

Answer:

C. Earth
