Is the earth flat?

[walrus]

Id like a couple of answers on very basic questions if possible please.
Why is there a curved shadow of Earth on the moon during an eclipse if its flat?
How are there tides with water rising and falling across the (excuse the expression):globe,which are running west to east at perfectly defined timed but varying intervals due to the moon if its dead flat and the argument is that the water is dead flat or level along with it?

good luck Andre but this is no longer about asking questions and expecting to get an answer I guess you need to hold a round ball of water for him.
