I was pacing back and forth in an empty plain where no one could see me, since we didn't built any houses yet. I was given two choices, should we leave or should we go? My people found this luscious land that gave us everything we could possibly need. Food, water, shelter...what more could we ask for? It has all our necessities, and we are pretty tired after traveling from place to place. 

This was the hardest decision ever. Not only because of the people, but because of the land itself. It may seem good now, but what about in the future? What would it be like in spring, summer, autumn, or winter? Right now, we're near spring, so you can check off spring on the list. As I looked around, I noticed that most of the people were already rejoicing. I smiled, looking at them thoughtfully. Maybe this is the place where we could stay together, and not have to move place to place. Maybe this could be our permanent home. After all that thinking, I finally made my choice. I slowly walked over to my people, stood on a sturdy rock, and said my words. They cheered even more, and I smiled, knowing that I made the right choice.

The Science Revolution is an important time in world history. "Why," you ask? Because all the scientists back then were the reason why we know so much today. 

Copernicus was a scientist who came up with the heliocentric theory. The heliocentric theory was a theory about the sun being in the middle, with the Earth and other planets circling around it. Kepler, another scientist, proved that the planets did not circle around the sun, but went around it in an elliptical, or oval, shaped way. Sir Isaac Newton made theories (also known as laws) about motion. He discovered gravity, and also predicted a force that held the Solar System together. Galileo Galilei made the heliocentric theory true in 1992, when Pope John Paul II accepted Galileo's theory, and admitted that he should never have been taken of heresy.
