True, but it also doesn't mean Sungenis is a good scientist.
Do you think Sungenis is wrong in claiming Geocentrism is the true state of the universe?
Because as far as I know currently, we still can't prove either Heliocentrism nor Geocentrism empirically, as all of your observations are relative to our frame of reference - we'd need a second frame of reference to actually find out. If we ever landed on another celestial body we could find out - there are going to be landings on Moon and Mars in the next few years if all goes according to plan, it'll be exciting to get all those new findings for sure.
Please correct me if I'm wrong.
Also, I know I'm opening a can of worms by saying this, but I find it difficult to take Holy Scripture literally in scientific matters. Take for example this passage from Genesis 1, 14:
14 And God said, “Let there be lights in the firmament of the heavens to separate the day from the night; and let them be for signs and for seasons and for days and years, 15 and let them be lights in the firmament of the heavens to give light upon the earth.” And it was so. 16 And God made the two great lights, the greater light to rule the day, and the lesser light to rule the night; he made the stars also.
On first glance, this sounds like a description of Sun and Moon in the poetic style of Genesis by a terrestrial observer. As we now know, the Moon is only reflecting light and isn't a light source per se, so how can this passage be taken literally? The same problem applies to all the other arguments regarding flat Earth, the Earth dome, Geocentrism and so on.
