I enjoy the openness of this question. Here are some that are known at this time, but no less fascinating.

- The earth is old. It is four thousand five hundred million years old. But that number, written just like that, does not viscerally show how old he is. It won't make your stomach drop. For that we need a metaphor.
- This is how Stephen Jay Gould summed up what McPhee said: "Consider the history of the Earth as the old measure of the English courtyard, the distance from the king's nose to the tip of his extended hand. A blow of a nail file in the middle finger erases human history. "
- All living things on earth are related. Life on earth is just a great family tree. You and a chicken, share a great-great-great-great grandfather. Like you and a shark. You and a spider of balls. You and a yeast cell. Your genes and the genes of a bacterium.
- The universe is vast. Our galaxy alone contains between 100 billion and 400 billion stars. The Hubble telescope once pointed to a dark and tiny region of the night sky in the area of the large ladle.
- The region is so narrow that a tennis ball, 100 meters away, could have blocked the view. The region did not contain stars from our galaxy; Then, looking at that region, we could see other galaxies. They took a picture of this small region, which covers only a 24 millionth part of the night sky. This is what they saw:

The image is called the “Hubble Deep Field”. Each of the dots you see is an entire galaxy, and each contains hundreds of billions of stars.
Maybe I’ll edit this to add more later. But for now, here you go!
Thanks For Reading
