unbalanced force
long range
The strength of the gravitational forces between the Earth and an object on or near it is called the "weight" of the object. In reality, there are two equal and opposite forces going on. The Earth attracts the object toward it, with a force that is the weight of the object on Earth. At the same time, the object attracts the Earth toward it, with a force that is the weight of the Earth on the object. The forces are equal. When the object is our body, we obsess about the first one. Nobody ever talks about the second one.
An object's motion can't change unless an external force is acting upon it. This is Newton's First Law of Motion.
Because you have to talk to Alakazam first. He's up toward Wiscash Pond.

We call that the "weight" of the first object when it's on the second object. Note that it's exactly equal to the weight of the second object when it's on the first object.
The exact scientific explanations of gravity are far too complex for this forum. The simple explanation is that every body that has mass attracts every other body that has mass. The more massive the two bodies are the more they attract each other. The more distant they are, the less they attract. Earth has a huge mass, billions and billions of times the size of a human. All of that taken together pulls everything and everyone toward the center of the earth. You may not be aware of it, but your body is also pulling the earth toward you. We can see the effect of a smaller body pulling on a larger one when we see the tides. The moon, a quarter of a million miles away, is affecting the water and the outer crust of the earth, even though the moon is only a little more than 1% of the earth's mass. Further out, tiny Pluto was discovered (in part) because it was affecting the orbits of the gas giant planets Neptune and Uranus.

Dinosaurs evolved first and then some dinosaurs evolved into birds. So all birds are technically dinosaurs.
Dinosaurs emerged first. Some dinosaurs were birds, but they didn't come until later.
