Barring you being an avid sky watcher, and mathematician, to your own eye, no. You have no empirical evidence in your own being that the earth is round, nor that the moon goes around the earth - You have been told that, and you 'know it' by way of accepting the evidences taught to you.
And those evidences are not empirical - No one has been able to tell me how I can look across 60 miles of water and see the other shore, which should be well below the horizon on a spherical earth... but we accept it anyway...
Likewise the evidences for Yahovah, and his Messiah. The evidence *for* is extraordinary.
There will always be flat earth folks. And there will always be those who deny the Father.
I know.
