How can an atheist have an opinion about the nature of what they conclude is a non-existent God? They would be better served to wonder what distinguishes man from all other known species.
What sets man apart is the rational "soul". It is behind the drive in man to find out the why of things he observes in the physicality of life. In so doing he is enabled to harness life's processes for his own purposes. For example it is not man's "natural" ability to fly as do birds yet man found a way to fly in airplanes. Man observed lightening and found a way to come up with discovering the use of "electricity" to provide light in cities and as a means of communication, and for many other uses. Yet scientific discoveries can either be used for constructive or destructive ends.
Science is mute when it comes to the right and wrong of things; moral vs. amoral, love vs. hate, or justice vs. injustice. Only in the realm of religion or spiritual philosophy are such concepts explored, concepts which goes beyond the mere physicality of existence.
Philosophy may be divided into two categories; spiritual and material. The philosophy of Socrates is an example of a spiritual philosophy whereas the philosophy of Marx and Engels, Communism, is an example of a material philosophy.
Religion may be divided into two categories or lines; that line from Abraham and that line from Krishna, Buddha and Zoroaster, both lines of which I consider valid and from God. On the other hand, I seem to remember it may have been Abraham who had three daughters; one of which prodigy came Krishna, Buddha and Zoroaster; one of which prodigy came Jesus stemming from Jesse, and one of which prodigy came Mohammad. As I recall, Baha’u’llah, founder of the Baha’i Faith, has a lineage which can be traced back to King David through a Persian King. At least in the line of religion from Abraham progenitor is considered an important principle insofar as prophecies are concerned.
What I would emphasize about the Baha’i Faith is its principle of the oneness of God, the oneness of religion, and the oneness of mankind. Its Founder claims to have come in fulfillment of all the religions of the past, and that its Revelation from God is not the last, and finally, that progressive Revelations from God through Prophets, or Manifestations of Goad, at intervals of about a thousand years, will continue to occur in accordance to the circumstances of mankind.
Mohammad is known as the “Seal of the Prophets” because He brought to a close the “Prophetic Cycle”, or the “Cycle inaugurated by Adam”. The Baha’i Faith, on the other hand, has inaugurated a new “Cycle of Fulfillment” to last no less than 500,000 years. As I recall, there has been many religious Cycles in the history of mankind even before Adam.
