Answer 1

The evidence supporting the Big Bang theory includes the formation of planets in debris disks, the movement of galaxies toward us, and the detection of background radiation in every direction.

Step-by-step explanation:

The evidence that supports the Big Bang theory are:

1. Planetesimals form in debris disks: This evidence shows the formation process of planets in debris disks, which is consistent with the way our solar system formed after the Big Bang.
2. Most galaxies are moving toward us: This observation suggests that the universe is expanding, which is a key component of the Big Bang theory.
3. Uniform background radiation is detected in every direction: The detection of cosmic microwave background radiation supports the idea that the universe began with a hot, dense state and has been expanding.
