in three to five sentences, evaluate the scientific evidence that supports the big bang theory and steady-state theory. make it sound like an 8th grader
The Big Bang theory is supported by many pieces of scientific evidence. Scientists discovered that galaxies are moving away from each other, which suggests that the universe is expanding. Radiation left over from the Big Bang, called the cosmic microwave background, has also been found. Additionally, the abundance of light elements like hydrogen and helium in the universe matches what the theory predicts. On the other hand, the steady-state theory doesn't have as much scientific evidence. It suggests that the universe has always looked the same and is not expanding. However, the Big Bang theory has more support from observations and measurements, making it the most widely accepted explanation for the origin of the universe.
