You are trying to confuse me but I'm alert. The problem is we
were not told about atoms and molecules. You got the facts wrong,
it is not that humans then did not understand, they were not told
and even with the brains that god gave us, humans then did not know
there were atoms and molecules till lately.
I am not trying to confuse you. I am trying to be as simple as I
can to explain to you the subtleness of His design. Even if you
were told then, you would not understand. But they exist
regardless of whether you are told or not.Atoms and Molecules are
just terms, given to explain what is already there.
The Bible simply expressed the seeming "creation" of man in
words that could readily be understood; in fact, the right term is
just as you put it - "put together."
Genesis 2:7
"And the LORD God formed man of the dust of the ground, and
breathed into his nostrils the breath of life; and man became a
living soul."
Man was "formed" and "breathed" and "became". How God did it we do
not know. Perhaps the so called existing matter? He
"doeth great things past finding out; yea, and wonders without
number" (Job 9:10)
Back then, they didnt know geohpysics , geotechnical and
seismic, all they did then was just follow instructions, and
booom... the walls of Jericho comes tumbling down.
Fastforward to now, we understood the WHY and HOW and what is
that ? Its called Seismic, its called Vibrations, its called
Frequencies.
Hope that further clarifies my points.
