"More than 95% of the energy density in the universe is in a form that has never been directly detected in the laboratory! The actual density of atoms is equivalent to roughly 1 proton per 4 cubic meters."

Be grateful for the complex life on Earth...
But very few of that mass is ordinary matter. Indeed, in the cited paper we read:
If you average out the entire cosmos, there is a total mass density of 9.9 x 10^-30 grams per cubic centimeter, which is equivalent to 5.9 protons per cubic meter. Note that I was describing mass density, however, not particle density. According to the latest data from the Planck satellite, only 4.8 percent of that density consists of ordinary matter, mostly hydrogen nuclei (protons). On average, then, there is 0.3 atoms per cubic meter of space.

We cannot separate ourselves fro THIS evolution.
A very interesting article on Aeon: There's no planet B
“We don’t just need a planet roughly the same size and temperature as Earth; we need a planet that spent billions of years evolving with us. We depend completely on the billions of organisms that make up Earth’s biosphere. Without them, we cannot survive.”

Abhay Vasant Ashtekar (born 5 July 1949) is an Indian theoretical physicist. He is the Eberly Professor of Physics and the Director of the Institute for Gravitational Physics and Geometry at Pennsylvania State University. As the creator of Ashtekar variables, he is one of the founders of loop quantum gravity and its subfield loop quantum cosmology. He has also written a number of descriptions of loop quantum gravity that are accessible to non-physicists. In 1999, Ashtekar and his colleagues were able to calculate the entropy for a black hole, matching a legendary 1974 prediction by Hawking. Oxford mathematical physicist Roger Penrose has described Ashtekar's approach to quantum gravity as "The most important of all the attempts at 'quantizing' general relativity." Ashtekar was elected as Member to National Academy of Sciences in May 2016.
Abhay Ashtekar is an atheist, though he enjoys reading on Indian and other eastern philosophy, namely the Tao and the Zen traditions. Furthermore, he believes to be inspired from the Bhagawat Gita as regards his attitude towards work.
