There are no essential molecules for life, except possibly water.

Not correct. Some bacteria can subsist on nothing except water,
inorganic minerals, and at least two specific chemicals that have
different redox potentials so that they can be reacted against each
other to yield useful energy. A symbiosis between such bacteria and
a type of photosynthetic bacteria can survive on nothing except
water, inorganic minerals, and sunlight.
All the adenine needed by life on Earth is synthesized by living
cells. Thus adenine is no more necessary than gazillions of other
specific chemicals also produced by life.
> Without it, the basic building blocks of life would not come together.
The building blocks of life don't "come together". They are
specifically synthesized by some life and absorbed by others by
preditation or seeping from the former.
> Scientists have been trying to find the origin of Earth's adenine
It's synthesized inside cells.

Bullshit!! Life exists on Earth because it existed yesterday and
life is pretty good at surviving from day to day, and has been
doing so for over thousands of millions of years. Life maintains
within itself a delicate combination of chemicals, which are *not*
ingredients in the sense implied by all the rest of this article
down to this point.

This is the only useful statement in the whole article.
