Can you help me identify it? Check out pics there...

Phew! That's a bit difficult - I'm native from France and it could be
so many trees! I first thought of a walnut. It's the right size for an
8 years old tree. Where about did you pick the seed from? A woodland? A
field? Where about in France? Ailianthus looks like this too ....
