Did we go to the moon? Absolutely, we left evidence behind that was testable. We were there. There is no doubt what so ever. Is the earth a sphere? Yes absolutely, the laws of physics and its own behavior confirm that it is. Beyond this, we are in space, satellites work, the ISS orbits the planet (I've seen it WITH MY OWN EYES and a telescope as it went overhead). These wouldn't be possible with a differently shaped planet... plus the variance in forces of a non uniform shape would be so easily detectable. People don't propose the earth is a sphere, its not a hypothesis, it's a confirmed scientific fact.
People that propagate the false hypothesis (yeah that's right, flat earth isn't a theory, because it isn't supported by REAL data) either want attention, are easily deceived, or are obsessed with finding out that they are being lied to.
I am getting kinda bored talking about this so damn often on Steemit.
