Who was the first human? Who was the first person that was the kind of ape we are?

There was no "first". When did you "first" become "mature looking"? There is a span involved. It occurred over many generations.

Fun fact, God originally called him "Boner", until he took a bone from him to make Eve.

Earlist known anatomically modern humans were in Ethiopia 230,000 years ago. That's the closest you're gonna get to a real answer.
If archaeologists agreed on a precise cutoff point in bone structure at which our species started, it's still highly unlikely that we would ever find fossils matching that.
Like how we have some idea of what the chimp-human common ancestor was, but it very likely lived in an environment that failed to preserve any fossils. Is is lost in time, never to be seen again

What do you mean? Which subspecies? It seems likely that sentience was first achieved among the great Bronze Age civilizations of the middle east region, then popped up independently in the China region and Europe (with a little help from Yamnaya genes). Most other extant hominids appear to have achieved sentience rather later, though there is no hominid population today that cannot grasp the use of stone tools.

>There was no "first".
Humans and apes have different chromosome counts, so no interbreeding is possible. Chances are that the last common ancestor had the same number as apes, since humans are a small part of the primates.
Thus the question is fair, and it also raises the question on how the first human could even breed and have offspring.

There's a lot of transition, that you probably wouldn't describe as human, between the apes you're thinking of and Homo sapiens

>There's a lot of transition
That is quite plausible. Nevertheless, there is a sharp boundary set bt the chromosome count. How to cross that boundary as a differemt species?

if you keep going back in time you're going to come across humans that have 90% reproductive success with modern humans, then 80%, then 50% etc etc

^This. There is no definite moment when humans appeared, evolution takes place over many many generations of a species, unless there is a catastrophic event that causes a rapid acceleration of evolution.

Historically speaking Lilith was created one day before Adam and made from clay as was Adam...When she bailed out of the Garden, thats when Eve was created, but not from clay but from bone.

>Humans and apes have different chromosome counts, so no interbreeding is possible.
Incorrect. It's very possible to interbreed with a balanced translocation. The rate of miscarriages will be higher, but other than that it presents no issues. So an ape can be born with a fused chromosome (total 47) and breed with other apes. Some of the offspring will inherit the fused chromosome and also have 47. These offspring can then breed and some of their offspring will inherit fused chromosomes from both parents, leading to 46. The same process has been directly observed in humans; there have been several 44 chromosome individuals with no negative effects.

The Time Travel Interpretation of the Bible
>https://vixra.org/abs/2104.0068
We describe the Biblical work of ages as a time travel program for saving humanity from extinction. God's existence is proven as a consequence of the existence of time travel, which is supposed. We present the case that Abraham's grandson Jacob, also called Israel, is Satan. We make the case that the Israelites are described as God's chosen people in the Bible despite their identity as the children of Satan because God's Messiah is descended from Abraham through Satan. They are chosen as the ancestors of the Messiah rather than as Satan's children. We propose an interpretation in which God commanded Abraham to kill his son Isaac to prevent Isaac from becoming the father of Satan. We suggest that God stayed Abraham's hand above Isaac because preventing the existence of Satan would also prevent the existence of Satan's descendant the Messiah. The history of the Israelites is summarized through Jesus and Paul. This paper is written so that the number of believers in the world will increase.

This is actually a very interesting question and an active area of research in evolutionary biology today, and it's a problem for evolution in general and not just humans.

That being said, I would disagree that we can make a definitive claim regarding the "first" individual of a particular species. The choice will always be somewhat arbitrary. In biology, categories and individual identities are always a little fuzzy.
