Beginning
Have you ever wondered what it would be like if you didn't exist? Or what it would be like to not exist. Or if there ever even was a beginning? Like, god, for example, who created him? When did he come into the story? When was he created? When was he created? Was there even a beginning?
Death
When you die, who knows what will happen. Some people believe every time you die, you are reborn as someone else. Some people think you go to live with God in heaven, or with Satan in hell. Some people think you just cease to exist. Can you imagine, being nonexistent? What would it be like? Would you just… sleep eternally without dreaming? Is there even a thing such as eternal death?
Humans
Some people think we evolved from monkeys. Others think we were made from God. Others think that we crawled from the sea as crabs and became humans somehow. If we evolved from monkeys, why didn't the other monkeys turn into people too? If we were made from God, who made God? If we were crabs who crawled onto the shore and became humans somehow, how did that happen? How do we know we aren't just like any other animal? We all look similar(ISH). We all speak different languages. We all live in specific places. How do we know the animals don't think that they are humans?
Universe
We all live in this universe that orbits the sun. But what created these planets? What created the things that created planets? So on. What was the beginning of all this? What is anything these days? Are we all just some things created by other things, that were created by more? What is anything in the universe?
Names
All the names in the world are made up. Cat, dog, mac and cheese, literally all the words in existence. We all started with basic things, but names are just made up. They aren't real. Just things people say to have recognition, and stuff like that. Everything that we say is a name, and that means everything we say is made up. Nothing is more made up than a name.
