Shouldn't we be making mummies of the dead?

Most people seem to be intrigued by Egyptian mummies.

I am sure that there are all sorts of reasons for this.

But generally speaking, the big reason is that it gives us a bit of knowledge about our very ancient civilized ancestors.
Which in turn stretches our present into our past, in an intimate fashion that can not be totally matched by the written record.

Which in turn puts us in our place as runners in a great relay race.

Which in turn (one would hope) would help maintain a certain humility and a certain (if not objectively proveable) connection if not obligation to the future.

But in our time, we burn “our” remains, or put them into porous boxes.
And we bury those boxes in some field somewhere.
Rest assured, in three thousand years, nobody will know much about us other than we had bones, and that is assuming that the bones have not already dissolved.

Don’t we sort of owe it to the distant future to make mummies of ourselves when we die?
