About Creation

B"H

The Talmud Tractate Rosh Hashana 11a teaches us that Adam and Eve (Chava) were created at the age of twenty.
The figure "20" is not necessarily to be taken literally, as the Talmud often gives us figures but actually does it in order to describe something. Twenty could also symbolically mean that the two were created as adults and not as children or teenagers.

There is no time whatsoever for G – d. He always existed and will do so eternally. Time was only created by Him when the world and humans came into existence. After Noach's Flood, the human DNA was changed again. Done as a punishment and from then on, humans had a much shorter life expectancy.

Our Sages explain that ONE day for G – d consists of 1000 human years.
A g – dly year consists of 365.25 g – dly days.
When a g – dly day consists of 1000 human years, then 365.250 human years make up one g – dly year.
