I know we think in terms of containers, but try to think of evolution as a gradient, like the spectrum of colors as seen in a rainbow. The colors transition subtly, but at any point along the gradient the color is nearly indistinguishable from the colors immediately around it. It is only when comparing at sufficiently distant points that we can see the hue distinction clearly. This is similar to speciation. Any particular organism closely resembles its parents and its offspring, but when you see it compared to its progeny 10,000 or 100,000 generations removed, you see significant differences. So, there's no first human with clear boundaries, just speciation from others that developed separately or are sufficiently behind or ahead on the evolutionary path.

Could you imagine being the first Homo in the world? You would have all that brain, but no one to share your newfound ability to learn and expand.

Sounds like you have a "back of the napkin" understanding of Evolution and Natural Selection, colored by some Ken Ham flavored Creationist strawmen.

Let me explain:

Human beings were not "created" in the sense that the computer I'm typing this one was. The very use of that verb implies what people on the Anti-Science side of this argument would refer to as an "Intelligent Designer" of some sort. The human species evolved over a period of billions of years from earlier species, with, over time, some generations acquiring small changes that made them and their descendants more successful in their environment. A huge stack of successive layers of these changes, spread out throughout the World, creates what we call the "Tree of Life".

Because evolution and speciation are matters of population mechanics, they do not directly affect individual members of the population. For this reason (hard to wrap your head around, I know), there was no "first human in the world" that you could point to. You could, theoretically, however, point to a first population of Homo Sapiens, the human species, but even that would be a bit fuzzy when dealing with a population close to the point of speciation.

Small changes over long periods of time. Micro over Macro.

The word “created” is misguided here, first, because implies the notion of a “creator”, second, because life is a complex process whit many elements interacting, even now we don’t have a fully convincing definition of life.

There is a mathematical proof that something can be created from nothing.There is still A LONG way to go to proving this, but it is a start. [medium.com] . Everything after the actual beginning follows the normal evolution cycle.

Well, he or she was born the mutant offspring of one of our ancestors, most likely the Homo Erectus.
