200,000 B.C. A time travel story

You awaken to the hum of solar panels activating under a scorching sun. The cargo container—your new home—sits amid a vast savanna, dotted with acacia trees and distant herds of megafauna: woolly mammoths, saber-toothed cats, early hominids scavenging in packs. It's 200,000 B.C.; no fire, no tools beyond crude sticks. The air is thick with dust and primal roars. Inside: stocked pantry (20 years' MREs, seeds), workshop with 3D printer, metal ingots, cloth bolts, thread, tools for forging/crafting. Library shelves bulge with manuals on survival, paleontology, physics, chemistry, biology—everything to bootstrap civilization. Defenses: reinforced doors, motion sensors, air-powered harpoons (ammo: 50 spears). Outside, a group of hunched figures—Homo erectus?—eye your metal box curiously from 100 yards away, grunting. No aggression yet, but hunger gleams in their eyes.
