ELI5 : Does a rainbow have a geographic position ?

Since a rainbow is sunlight diffracted through rain, is it seen at the same place for everyone or do we see it somewhere depending on our current position ?

No, the position of a rainbow depends on your current position. All observers will see it as a 'circle' with its centre opposite the sun. Run 100m in any direction and the rainbow will still appear at the same angle to you.
