was it discoverd in earth's crust?
or made in a lab?

...Aluminium is found primarily in bauxite ore and is remarkable for its resistance to corrosion (due to the phenomenon of passivation) and its light weight.
It is mined in ore form.
Yes, is the answer.

Here we go with aluminum again.... ;)
Aluminum is abundant in a compound in lots of places around the world that are hot and wet, like near the equator. This compound it is in is the mineral bauxite.
Aluminum is removed from the bauxite using some processes and reactions. I might be wrong about this, but I think the actual reaction that isolates the aluminum is called the "Hall process". So....it was discovered in the earth's crust as an oxidized metal ore (kind of like iron ore was) but at the same time a chemical process had to be developed to get it out.
Hope this helps.

Aluminum is a natural element. Besides a few synthetic isotopes, it is only really the atomic elements above 100 on the periodic table which were created in a lab

It's natural, but it forms within other rocks, so they have to separate it by melting it out, this is called refining.

yes it is natural
it occurs in nature primarily as bauxite ore from which it has to be extracted.
