Copernicus
Galileo Galilee
Nicolaus Copernicus first said that but when he did at first no one believed him until sometime after his death.
Copernicus proposed a sun centered solar system Galileo supported his belief.
Nicolaus Copernicus was the scientist who first proposed the heliocentric model of the universe, suggesting that the Earth rotates on its axis and moves around the Sun in a complete year. His work challenged the geocentric view that the Earth was the center of the universe and revolutionized our understanding of the solar system.
The first scientist to dispute the geocentric model of the universe, which posited the Earth at the center, was Nicolaus Copernicus. In the early 16th century, he proposed the heliocentric model, which placed the Sun at the center of the universe, challenging the long-held views of Aristotle and Ptolemy. His seminal work, "De revolutionibus orbium coelestium," published in 1543, laid the foundation for modern astronomy and shifted the paradigm of celestial mechanics.

That would be Alfred Wegener
Nicolaus Copernicus, a Polish astronomer, proposed the heliocentric model in the 16th century, suggesting that the Sun is at the center of the universe with the Earth and other planets orbiting around it. This idea challenged the prevailing geocentric model, where Earth was considered the center of the universe.
A German scientist Alfred Wegener first proposed the idea of Continental Drift.
Arthur Holmes
