Through different moon phases, it's clearly obvious that a round dark (doesn't emit light) object is blocking Sunlight rays from the moon. This is an adequate proof for me, seen with my naked eyes every day, that Earth is round.
Not quite dude, Moon Phases are not seen because of earths shadow on the moon but rather earth/moon/sun position relative to each other in their orbits. What we see on earth is the reflection of sunlight from the moons surface. When the moons orbit is "between the earth and sun" than none of the surface of the moon reflects sunlight that we can see, therefore we don't see the moon basically (New Moon). As the moons orbit moves it towards the "back or earth between moon and sun" much more of the sunlight reflected and finally a full moon appears in the sky.
Don't use "between x and x or back" literally please, they're used to describe general locations.
And you were correct about moon phases being 1 of the millions of ways we have proven the earth is a globe and something you can see with you eyes. But the science behind your reasoning was wrong so I thought I would point that out.
