The God Tree is similar to both the world tree and the tree of life, motifs that are present in several real-life religions and mythologies throughout the world
The God Tree bearing the fruit that was deemed forbidden to consume is very similar to the story of the Tree of the knowledge of good and evil in Abrahamic religions, in which Adam and Eve, the first humans, ate the forbidden fruit despite being told otherwise. Ultimately, while becoming wiser, it lead to their downfall by incurring the wrath of God. For disobeying Him, He forever cursed the two and their descendants. Adam's eldest son, Cain, would later murder his younger brother, Abel, in anger and jealousy following God's rejection of his offering while accepting Abel's, similar to the struggle between the two sons of the Sage of the Six Paths.
The wooden dragon-like entities at the base of the God Tree may be a reference to Nidhogg, a dragon or serpent who eternally chews the roots of Yggdrasil in Norse mythology. Likewise with the appearance of the God Tree, it is said that should Nidhogg finally be free of its entrapment underneath Yggdrasil, its appearance into the world beyond its roots are said to herald the coming of Ragnarök, the end of the world and ultimate battle of the gods.
