Only fools say with confidence what is unknown. For example, the outer-most layer of Earth is considered, 'Land'. Water naturally rises and falls for expanses of 'Time'. That's why there are underwater 'roads'. Greece is a great example, as similar Greek stones, roads, and sculptures still exist underwater at varying depths right outside of existing cities.

What is the science behind female male attraction? Why some people love that one perticular person over other. Is there any explanation for that
