Yes those ancient men knew so much more than us today.
Have you taken into account that ancient primitive men thought that earthquakes, floods, lightening, thunder etc. were caused
by Super natural gods and not only in the middle east where most of the bible was written, have you ever accepted wholly the
human ignorance factor, truly and honestly ?
It would be fool hardy to not be in awe of the universe of what we have perceived to date, it is also fool hardy to proclaim its
creator without any evidence.
And no black holes are not physical proof of a god , just as we found that the sun is not god .
