Photos from space.
The fact that if you start out at any point A and move away from it in any direction you will eventually end up at point A again.
The horizon seen from a high flying plane is a curve and not a straight line.
The shadow of the earth against the moon makes a crescent shape, hence the object casting the shadow (earth) is round.

1) One of the evidences given since ancient times about the spherical shape of the earth is the shadow of the earth during lunar eclipse. Only a spherical object can produce a circular shadow. Others will produce an elliptical or oblong shape. If the earth had been flat with a circular shape it would produce a oval shadow rather than a round shadow.
2) If you stand at the port and watch an approaching ship the mast of the ship appears first. this is also an evidence of the spherical shape of the earth. If the earth had been flat or any other shape then we would not really be able to see the approaching ship mast first.
3) If a journey by aircraft is made from one point on earth towards east or west keeping the direction same one would return to the same point
4) The pictures taken by satellites are final evidence that the earth is spherical.

Rabindra has given a good answer. But it is interesting that so many people have mentioned photos from space. Of course, we knew that the Earth was round long before there were any space satellites or shuttles. So there has to be other good evidence, doesnt there. And anyway, photos can always be faked, so they arent really good evidence.
One piece of evidence is like this: every day a million planes take off and head for a different part ofthe earth. They all navigate with maps and systems that are based on the idea that the earth is a sphere. If it weren't a sphere, none of them would ever arrive! Their navigation wouldnt work. But, they do arrive exactly as they expect. So that is a powerful evidence that the earth is, as the navigation systems assume, a sphere.

all the evidence in the world. lol. all the people that go into outer space, they have a perfect view of the earth. They send pictures back so we can see. It is definetely round

Evidence from photos taken on missions to space. The eclispses are another.

the fact that there is a horizon... the fact that we've sent people to space and they've seen the earth (and photographed it)... the fact that planes fly routes based on a round earth... that's all i can think of now, good luck...

Day and night. Photos from the moon. Eyewitness accounts from astronauts.

Em, the fact that no 'explorers' ever actually sailed off the edge. They follwed their compasses (compaii) and kept going and ended up back where they started. It were Magellen who first circumcised the globe, weren't it? (or was that 'circumnavigate'?)

well the astronamers in the space shuttle saw the earth
also we have satelites looking at the earth at all times

satellite imaging, photographs showing the the curvature of the earth, i think that is conclusive evidence
