Before Christ (BC), Earth was dominated by vast landscapes of forests, mountains, deserts, and oceans, varying significantly across different regions. The continents were positioned differently due to plate tectonics, with some landmasses connected while others were isolated. During this time, diverse ecosystems thrived, home to a wide range of flora and fauna, including dinosaurs in earlier epochs and early mammals as time progressed. Human civilization began to emerge towards the end of this period, with the development of agriculture and early societies.
