Source? Yours?

Michelangelo (Lodovico Buonarroti Simoni) had shown you 2 (or more) triangles changing its ideal forms into opposite changings (1 higher other lower) into base of your form ... (what already earlier did it on pyramids, much more 30k years ago).

What has triangle ? Well, it has everything, from base to your 2d-polymers from Monomer (=Triangles form) to your dna-proteins from 2d-polymers... including almost everything others create (on base of own creation).

Well, there are other rules why you/all creatures appeared, influences for triangles first creations and later effects of combinations of them. There are other forms: and those "suck" your life... you don't believe? I don't care ... graves are fulling (filling) more and more : ) and that's beautiful.

Human cells are important : ) isn't it? : )

Time gives answers for revenge, 120 caskets every one minute time, 2000 years ago 3 every minute, .... so:

7000 years ago have been 5 million people on earth and built all those 2-20,000 pyramids?

Or 40,000 years ago have been ?

Or 100-300,000 y.a ?

I still haven't told you the future :), but it will be fun, the next 1,000 years.

You needed something to take the blame.
