Actually Aristole didn't conclude this theory. Gallileo proved the Earth was round. Eratosthenes of Cyren put the idea out in the open, but Nicholas Copernicus and Galileo Galilei showed the theory to the public.
hello
A boat at sea, alone, does not prove that is earth is round. However, boats can be used to prove that earth is round. This is because if the earth was flat, eventually a boat would sail to the end of earth and fall off the edge. This has never happened, so it can be inferred that the earth is round. Also, a boat can sail all the way around the world and end up right where it started, which proves that the earth is round.
Because during a lunar eclipse, Aristotle observed that the shape of the earth was round.
Because of Newtons 3rd Law
Galileo Galilei

Because Earth's history is 4.567 billion years old, you can conclude that an Earth eon covers a large segment of time.
Aristotle concluded that the Earth was spherical based on observations of the Earth's shadow during a lunar eclipse, which always appeared round. He also noted that the stars visible in the sky changed as one moved north or south, suggesting a curved surface.
umm: "The Earth is round"? ------------------------------------------------ The Earth is not round - it is an oblate spheroid. ---------------------------------------------------------------------------- A (slightly) oblate spheroid seems pretty "round" to me.
He was a philosopher

The moon rotates round the Earth.
We can conclude that the density of the core and mantle are higher than that of the crust.
