ELI5: Why do people say that the "Separation of Church and State" is nowhere in the US constitution?
gpt
In part because that text "separation of church and state" is nowhere in the constitution.

The reason it's a discussion at all is because some people say the phrase (in the 1st amendment) "Congress shall make no law respecting an establishment of religion" implies the government cannot interact with religion.  Others interpret that to mean the government can interact with religion as long as it doesn't "establish" one, like how how england established the church of england.

You can interpret supreme court decisions to vary on exactly where the line of "establishment" goes.  They have ruled that schools cannot require students participate in prayer, but normally when free speech (the other major part of the first amendment) might be violated, they have allowed government and religion to interact.  They also do not require religious institutions to pay taxes (as they are legally non-profit charitable organizations).

Tried to do that without any bias, let me know if you have any other questions.
