OK so I LOVE riddles and thought it might be a bit fun to have a few on here. After someone has answered this perhaps they could post a riddle of their own.
OK here goes:
I am older than history, and will never die,
My lifespan is infinite, I cannot lie,
You may try to measure me, but you will not succeed,
Every day, every second I sew a new seed
And just in case your wondering this is my own which I made up myself - hoping it might be a little more obscure, but I guess we will just have to see
