No. The first time a human existed was when they got a human soul. That's one of the things that makes us unique.
Infusion of the soul occurred when God said "let us make man in our image", and "breathed the breath of life" in to him, to make him "a living soul" (nepesh); the rational, immortal soul (not shared by any animal) is the image of God; becoming Christ-like, that is, holiness, is the likeness of God. Man did not exist before he had a soul; souls did not exist before man existed. The two were created at the same time, and this is as far as the Church proclaims (that we are descended from original parents, and the universe/multiverse was created ex nihilo: "We believe in one God, the Father Almighty, maker of Heaven and Earth, of all things seen and unseen"...); as to date it, this is an impossibility in any model of creation, whether you believe in a young universe (and/or earth), an ancient universe (and/or earth), are a progressive creationist, a strict creationist, a theistic evolutionist, or an intelligent design advocate.
Essentially this - the soul makes the man, by definition. Beyond that, I'm not a believer in evolutionary doctrine/the modern Darwinian synthesis (pardon the pun), but when man first got a soul is simple: it is when man first came to be. As for when man first came to be, that's the challenge to answer. You can chime in with me and read Genesis and the genealogies literally (which still doesn't allow precise dating of Adam, as Genesis is silent on how long he was without Eve, and after that, how long until they Fell); you can hew to theistic evolutionary doctrine, to progressive creationism, to the framework hypothesis, to any of a hundred varieties of old-earth creationism, to intelligent design (i.e. evolution with God strapped on), and I'm sure there are plenty more - none allow the date to be precisely fixed, and for those that lay claim to a common ancestry/common descent, one can only date it very inaccurately, to "modern man" (likely sometime in the last 500ka according to the commonly used scientific/geologic dating system; cut two zeros off the end and you'll have a more accurate answer).
