Buddha is a God or different God's level misconception in Buddhism System
You can portray Gautama Buddha as an ordinary man who lived 2500 years ago, who found the way to end suffering and attain true happiness.
He discovered that suffering is mostly a mental condition. Thus, Gautama Buddha became history's most illustrious psychologist.
To support this claim, you can quote the first 6 verses of the Dhammapada. Part of these verses sound similar to Jesus' turning the other cheek, thus making Gautama Buddha appear compatible with Jesus in just this way.
Also, statues of Gautama Buddha are just for inspirational purposes, similar to statues of Abraham Lincoln, Martin Luther King and Mahatma Gandhi.
