Ooh! I just can't resist this stuff. It is like taking candy from a baby.

No!!! because a valence of four imparts the ability to form numerous
bonds. You can bond four hydrogens (and get methane), or double bond
with carbon, or oxygen, or nitrogen, etc. Wow!!! do you think the
variability had something to do with it? Biologic systems require many
different structures and functions to exist, funny thing, you can get
carbon to do that at the temperatures and pressures found on the earth.
Isn't this amazing!!!

Something else for you to read before you will become literate, basic
biology and chemistry texts.
