(Revised
according updated number of galaxies in the Universe.)
Life on Terra,
Planet Earth, has existed 4.1 billion years.
The whole primate
genus Homo has existed only 2.8 million years. The entire H. sapiens species has been
around just 200,000 years. The H. sapiens sapiens race (subspecies),
aka “modern humans”, is only 30,000 years old.
H. sapiens sapiens
is the only remaining race of the H.
sapiens species, with the other races (H. sapiens denisova, H. sapiens
idaltu, H. sapiens neanderthalensis), being extinct. The other species of the genus Homo—H.
naledi, H. habilis, H. erectus, H. rudolfensis, H. heidelbergensis, H.
floresiensis—and other genera of hominids—Paranthropus, Australopithecus,
Kenyanthropus, Ardipithecus, and Orrorin—have been extinct
even longer.
Genetic testing has proven that “modern humans”, H. sapiens sapiens, mated and bred with
members of earlier human species at least as old as H. habilis.
A single human of the H.
sapiens sapiens race is, on average, 664 billionths (0.000000000664 or 6.64
x 10-11) km3 in volume, with an average lifespan of 67.2
years.
There are 7.3
billion H. sapiens sapiens individuals on Terra (Planet Earth).
Forty billion of
the 200 billion stars in the Milky Way support Class-M planets and 8-10 billion
of these host sapient life analogous to humans.
If Terra’s current
human population is the median, there are 61.6 quintillion (61.6 x 1018)
sapient beings in our galaxy.
There are around 2
trillion galaxies in the Universe.
Hypothesizing the
Milky Way’s sapient population as the median, there are 123.2 nonillion (1.23 x
1032) sapient beings in the Universe at any one time.
Think about those statistics next time someone talks about,
or claims to be or to follow, the Anointed
One, the Chosen People, the Exceptional Nation, or the Elect Species.
