 How Long Is a Day of CREATION? 


Know your CREATOR, know yourself and know the difference






In our quest to study the IDOLATRY Commandment

We went to Moses’ Ten Commandments

Where the prohibition of idol worshipping

It listed as the Second of the Ten.


In it,

The idols are defined as “other ELHM’,

Inferring that we must first know ELHM

Then to decide who is NOT ELHM


For that,

We went to the First of the Ten, where the Speaker

Presents Himself as

I Am


Who took you out of Egypt Land


And we asked,

Who is YHVH? Who is ELHM?

And we went to Genesis Chapter One

Where those Names are presented the first time

And, therefore, are defined.


The Name ELHM, we found out,

Refers to the All Mighty  JUDGE,

Who is presented 35 times in the Chapter


Who seeks and follows the Absolute Truth.


If so, we’ve said, the story of Genesis must be true,

Since otherwise it would negate the meaning of the Name.

So, is the story true?


Then we showed that Genesis can’t be count

Among all the Bronze Age myths told in Moses’ time.


Now, can we match Genesis with our Science?

Having identified ELHM’s ways,

We ask: How long was a Day of CREATION?






1: How old is Creation?


Kabbalah’s calculation



 Science says, that the Universe is 13.7 billion years old,

starting with a Big Bang.

What does Moses say?


According to the Torah,

the murder of Abel by Cain occurred 5782 years ago.

and many use it as indicative of the Universe’ age.


But in fact,

The number 5782 does not cover Chapter One,

Which describes the Six Days.


Kabbalah says,

that Chapter One should be counted separately.

An ancient Kabbalah tradition, recorded by Rabbi H. Abulafia (13th century AD)

Calculates the age of the World from Psalm 90.



Composed by Moses, rather than David,

That Psalm says:

“For our thousand years

are like one day in your eyes.” 

Hence “One Day of the CREATOR” equals 1000 of our years,

and one year of the CREATOR equals 350,000 of our years (350×1000)


Since another kabala source teaches that

6000 Years of the CREATOR equal a Day of CREATION,

it comes out that

A Day of CREATION Equals 6000×350,000=2.1 billion human years.

And Six Days OF CREATION equal 2.1 x 6 = 12.6 billion human years


Another similar kabala  calculation

Comes out with 15 billion human yeas,

Making the average age 13-14 billion years,

Very close to the age that science says.




2. The Length of a Day Supported by the Text



The Torah’s text itself suggests,

that a Day of CREATION is a stage

in the history of the World.



  At the end of the First Day, it says:

“And ELoKiM saw that it is good, and

it was evening and it was morning,

 one Day.” 



We may observe that

The Torah calls the first Day One Day,

despite the fact that the Sun and the Moon

would appear regularly much later, on the Fourth Day


The First Day is called ‘One Day’ instead of ‘Day One.’

All other Days are called in their proper numerical names

,as Day Two, Day Three and so on.


It shows that the Torah defines for us

the length of ‘One Day’ of CREATION.


How long was it?

The time it took CREATION advanced from the ‘Beginning’

to see in it “Chaos, Matter, Abyss, Light and Water”

as mentioned in the verse.

That length could be 2.1 billion human years, as Kabbalah calculates.


Thus, a Day of CREATION refers to an era,

a phase in World’s history.

On the average, it lasted 2.1 billion human years.

Certainly, it was NOT our one day.


So far, Moses’ Story CAN be matched with science

something you can’t do with any of the myths of his time.


Can we also match the rest of Genesis with Science?
