Not only do we share lineage with anthropoids, but our ultimate precursor is stardust.
A STREAMLINED VERSION OF OUR LOCAL CORNER OF THE UNIVERSE'S HISTORY (SOLAR NEBULA HYPOTHESIS) :
A gravitational pull towards the material inside a rotating nebula causes a primordial cloud to form the shape of a flattened disk. Matter continues to migrate towards the center, forming a proto-Sun which collapses the nebula. This breakdown forms the solar system and a thermonuclear chain-reaction (fusion) that drastically increases the new star's temperature. Planetesimals cull to form the inner planets; disturbances in the residual planetary disk form the outer ones.
Five billion years ago, the Earth, much smaller than it is today, is augmented by the onslaught of Planetesimals and meteorites. Dense elements "sink" to beneath Earth's surface to form its liquid-iron core. The planet accrues an atmosphere of ammonia, hydrogen, methane, and water. With no ozone layer, the sun's rays roused this amalgamation to form amino acids and other organic compounds. They aggregate, and form the first cells (anyone care to enlighten me as to how genetic coding takes place?). We know of the first prokaryotic cells proliferating roughly 3.9 billion years ago.
These cells grow more complex, forming nuclei, dropping its complex cell wall in favor of tiny organelles and ultimately amassing to form multi-cellular life; the plant and animal kingdom is born. By the late Cenozoic (5 million years ago), we see these hominoids evolving into upright and ground-dwelling Miocene, the sole genus from which humans evolve. The first sapiens are seen in the form of the Neanderthal, circa 100,000 years ago, which die off 40,000 years ago with the influx of other sapiens like Cro-Magnon. The Neolithic Revolution, the introduction of farming settlements and domestication, ensured humanity's long term survival. Since then, Homo Sapiens have had a detrimental effect on the planet's ecology and threaten to destroy all of their progress.
GENESIS "THEORY":
The world - its features, oceans, life, etc. - was "created" and reckoned with in the matter of seven days.
Religious affiliation: Deist raised by Christians.
That set aside, I'd like to state that formulation using the Drake Constant, developed in the 1960's, has, with variables, calculated that perhaps a million sentient alien races with technological capability at or above our level exist in the Milky Way. Many doubt this, notwithstanding the galaxy's hundreds of billions of stars. If the SETI project ever contacts one of them, there is a 99.5% chance that they will be technologically and perhaps physically cognitively superior. Will they be friendly, willing to embrace humanity? We hope so ...
NOTE: All UFO discernment is either one or more of the following: erroneous observations, frauds, and delusions. It's dubious that any sentient aliens live nearby, that they have a humanlike physique, that possess starships that can penetrate our Oort cloud ...
NOTE: I havent bothered to spellcheck this bulky message; absolve me of all criticism.
