A Correct answer
Explanation

Edwin Hubble provided the first observational evidence for the Big Bang theory in 1929 by discovering that galaxies are moving away from each other and that more distant galaxies recede faster (Hubble's Law). This expansion of the universe suggested it began from a single point. While others developed theoretical aspects, Hubble's astronomical observations were the foundational evidence.
