the basics of evolution although the Bible never adresses the issues of evolution, pro or contra
Please note - there are 365 DAYS in a common year. In a leap year you get 366 DAYS. In a lunar year 354 DAYS.
Whatever calendar you are on, those DAYS get grouped into months. We are most familiar with the 12 month calendar - so I'll say 12 months pass and that group of months is known as 1 year.
Now whether you believe it or not, the Bible states that Adam lived for 930 years. Therefore there must have been a DAY when Adam was created from which you start to count the 1st year of his life.
It is the same concept of a child being born. When it is born, it has not evolved. It has grown in the mother's womb for 9 months, then the point of birth is counted as it's birth day. Once the child has lived outside of the womb for 12 months it has lived for 1 year.
The Bible does not describe Adam as being in the womb for 9 months but created in one day. Thereafter living 930 years, then dying.
Now you don't have to believe that. That is your choice but the description of Adam's creation in the Bible firmly rules out evolution.
