I have had my last two sheds on tanalised wooden bearers. Very easy to
lay,
lets the air circulate underneath and keeps everything dry.

Including rodents?
Perfect nesting conditions.

I'd put down some gravel and make sure it was well flattened. Put on a layer
of thick blue polythene and then lay your paving slabs on this. (If they
aren't quite level get one bag of pre-mixed mortar, mix with water in your
wheelbarrow and use to make four small "dollops" under the corners of each
slab.)
The polythene will stop much of the damp rising from the ground to rust your
tools.
We painted the bottom of the shed panels with bitumen - you can get a small
tin for a fiver.
