I would leave them a portable hard drive (containing all of our most vital knowledge and experience it could fit) encased in material which could
protect it from electromagnetic damage, encased in some sort of airtight, corrosion resistant, and hardened container (perhaps glass?), which itself
would be encased in a titanium capsule depicting the structure of atoms and the actions of electrons, etc. including etchings of mathematical formulas
having to do with electricity and the storage and transformation of data.
This capsule would be further encased in a larger titanium shell containing similarly protected stone tablets which would be etched with formulas and
writing, including a key to deciphering the tablets.
This last capsule would then be encased in a stone block, with an enormous stone structure engineered to be the most stable stone structure possible
with modern technology, and both inside and outside the stone structure would be every kind of artistic representation capable of filling its surface,
if for no other reason than to merely get one's attention.
This structure would be placed in an environmentally stable and friendly location to enable it to last as long as possible.
Finally, the most inner titanium shell would be sealed in such a way as to not allow anyone access until they acquired similar technology to our own
which would enable them to do so.
If costs allowed, I would have several of these placed in various locations both in, on, and off planet.
