Sundering Titan

Can you cast {sundering titan} if you have no basic lands in play?

I think I just found out the lands don't have to be yours. Is this right? And if so then there HAS to be a land of each type for it to be cast?

The lands don't need to be yours and you do not need all five lands to be present.

12/1/2004   Sundering Titan's two abilities aren't targeted. When one of the abilities resolves, the Titan's controller must choose one land for each basic land type (Plains, Island, Swamp, Mountain, and Forest).
12/1/2004   If one of the basic land types isn't present, it isn't chosen. If the only land of a certain type is one you control, you must choose it.
12/1/2004   If a land has more than one basic land type, it can be chosen more than once.
12/1/2004   All the chosen lands are destroyed simultaneously.
