Then why is it unreasonable to believe the human species originated with one couple?
It isn’t. It’s the only rational explanation for the existence of humanity.
However, it does appear to be unreasonable to those who imagine themselves as naked apes, and don’t really want to stray from that box.
In addition to our capacity to love (not the feeling), the existence of mathematics, morality, philosophy, the arts, science itself, in our search for truth is what separates us from other creatures with which we share the earth.
Although unrecognized by some, we are on a journey to the Truth who is the source and purpose of our existence…
Our efforts to determine who we are and where we came from are limited by our finite knowledge in time and space.
Assisting us is our intellect, which enables us to go beyond the appearance and discover its underlying structure.
We have also an innate awareness of our own being and, through the grace of God, some degree of connection to the Divine.
We here demonstrate the additional quality of being able to communicate and share our knowledge.
An understanding of where we come from physically speaking, can be gleaned from the record we find in the ground: monuments, ruins, artifacts and implements, bones and so forth.
The historical record, the most important being scripture in regards to our relationship with God, gives the stones and objects meaning.
In our search, beyond history and whatever remnants remain, we are left with time’s disorganization of what was.
At that point, we can draw on morphological data from the fossil record to tell us of our physical development.
It has something to say of emergence of skulls with sufficient volumes to contain a brain large enough to allow for the complexity of the rational mind.
We may be able to imagine how God may have fashioned us, stretching back to the beginnings of the dust itself.
The beginnings of Homo spiritualis (as opposed to the term H. sapiens) lie hidden behind a veil, revealed in scripture, which tells us only what is important to know.
There is a record that we carry in our genes.
Genealogical studies are only as good as the data, which is not some raw yes or no fact, but the outcome of analyses that strive to decipher the vagaries of the human genome.
Their value in providing information about our past is only as valid as the assumptions we use to bring the data together.
Today, one is the notion that that we are merely primates, evolving as a species.
Modern science has taken a wrong turn; and as a result, we find that what is perfectly rational, grounded in the truth, is portrayed as being unreasonable.
