Then around 340 BC, a Greek philosopher named Aristotle made the discovery of a few of our most important and fundamental theories that helped to further prove this idea. Aristotle first proposed that one always witnesses the sails of a ship approaching past the horizon first and then its framework. This suggested that the spring up of the ocean must be curved and not flat as it was once thought to be. Secondly, Aristotle discovered that the eclipses of the moon were generated by the shadow that Earth casted on it. This further proved the point that if the Earth was flat, the shadow it casted upon the stargaze would not app... ...years later that non-uniformity in the antediluvian commenced the formation of galaxies and ancient stars out of pouches of gas condensing due to gravity. Approximately five billion years ago, su ch pouches of gas that resided in a spiral channel of the milky Way Galaxy formed the Sun. An immense circle of gas and stand firm that was whirling around the ancient Sun formed to the planets, Earth included, which is predictably 4.6 to 4.5 billion years old. Works CitedAdskin, Alaina.
