Its possible that the earth was much much smaller and as a result had less gravity and allowed life to grow much larger, over time the earth cracks and expands and becomes larger, increasing its surface area over all which might cause life to grow smaller, instead of the once larger statures of life.
You do bring up a good topic for discussion. I guess many people think along these lines who can go beyond their thinking about Jesus Christ or Yahweh to the beginning of the White race. Everyone has their views too. Not a good topic if you want to avoid stepping on toes or sounding like a nut. Still I always think I am listening to a nut every time someone speaks to mre about Yahweh or Jesus Christ because they did nort come from the White race. We were the Kings in Egypt. Wait, I am going beyond that line and will not discuss it and... you are doing it fine.
2020 is a Christian Era date, not the age of the White race upon the earth.
Yggdrasil comes to mind.
LOL they are ugly as HELL and Stink and block the view of all that could be pretty.
