It's the highest form of science, that's why the watcher fallen angels were obsessed with creating hybrids (old world god pantheons were watchers, Enoch connects our forgotten history). They were already +5th dimensional beings so time travel and and alchemy are boring sciences since it was as natural as walking for them. While man made art in the 2nd and 3rd dimensions (paintings, buildings) the angels did so in the 4th dimension. Life itself.
