In The Chaldean Account of Genesis, by George Smith, [1876] we see the truth of what Adam means. It doesn’t mean the first man, but it refers to a race. Here is a quote showing you what race.

"the Babylonians recognized two principal races: the Adamu, or dark race, and the Sarku, or light race, probably in the same manner that two races are mentioned in Genesis, the sons of Adam and the sons of God.” (Ref 1)

As you can see Adam doesn’t mean mankind. This disproves the original sin narrative. Since we did not inherit sin from Adam there is no Messiah coming and there never was one to be a sacrifice for mankind. For those who think we descended from that race the Babylonians referred to as Adamites is the evidence completely destroying that lie.

"Seven thousand five hundred fifty-six (7556) haplotypes of 46 subclades in 17 major haplogroups were considered in terms of their base (ancestral) haplotypes and timespans to their common ancestors, for the purposes of designing of time-balanced haplogroup tree. It was found that African haplogroup A (originated 132,000 ± 12,000 years before present) is very remote time-wise from all other haplogroups, which have a separate common ancestor, named β-haplogroup, and originated 64,000 ± 6000 ybp. It includes a family of Europeoid (Caucasoid) haplogroups from F through T that originated 58,000 ± 5000 ybp. A downstream common ancestor for haplogroup A and β-haplogroup, coined the α-haplogroup emerged 160,000 ± 12,000 ybp. A territorial origin of haplogroups α- and β-remains unknown; however, the most likely origin for each of them is a vast triangle stretched from Central Europe in the west through the Russian Plain to the east and to Levant to the south. Haplogroup B is descended from β-haplogroup (and not from haplogroup A, from which it is very distant, and separated by as much as 123,000 years of “lat- eral” mutational evolution)

likely migrated to Africa after 46,000 ybp. The finding that the Europeoid haplogroups did not descend from “African” haplogroups A or B is supported by the fact that bearers of the Europeoid haplogroups, as well as all non-African haplogroups do not carry either SNPs M91, P97, M31, P82, M23, M114, P262, M32, M59, P289, P291, P102, M13, M171, M118 (haplogroup A and its subclades SNPs) or M60, M181, P90 (haplogroup B ), as it was shown recently in “Walk through Y” FTDNA Project (the reference is incorporated therein) on several hundred people from various haplogroups.” Klyosov, A. & Rozhanskii, I.
