Geremia is absolutely correct in my mind to disagree that the creation of light before the sun is a 'scientific contradiction.'

That there can be no light without the sun is wrong even from the standpoint of modern science.

Dr. Robert Sungenis: "In actuality, the Light of the First Day is the original light, but on the Fourth Day the sun and stars were either formed from it or were created separately....the Bible insists that the original Light that was made on the First Day still exists in the universe today.     There are other people who believe Evolution is a scientific fact.  They believe the universe is at least 13 billions of years old and the Earth is 4.5 billion years.  some of them also believe Genesis is a sacred record of how the world began, but insist that we are not to take every word of it literally.  Hence, although they believe Genesis ! might be read in chronological or a semi-chronological order, they hold that each of the Six Days is actually billions of years long.  This is also an incorrect way to read Genesis.  The word 'Day' in the original Hebrew refers to a 24 hour period, not millions of years.     .....some who hold to the Big Bang theory (which claims that everything in the universe came from a giant explosion some 13 billion years ago) believe that the creation of Light on the First Day refers to an immense primordial explosion which produced light.  This is also an incorrect way to read Genesis.  The first verse of Genesis insists that the Earth came before the Light, while the Big Bang claims that the Light came before the Earth."

.
This is the beginning of problems for big-bangism. 
.
It is impossible to believe the Bible and to also believe in big-bangism.
.
God created the earth on the first day but did not create the sun, moon and stars until the fourth day.
Meanwhile, from the first day there was light, the earth had night and day, but there was no sun. 
Sun, no, daylight, yes!
There was no sun on the second day, no sun on the third day, but the earth already had fruit-bearing plants, which need daylight.
The earth's plants were bearing fruit (meaning they were created fully mature in one day) but there was not yet any sun.
Not until the fourth day was there sun because that's when the sun was created.
.
None of this makes one bit of sense to the wrong thinking of biological evolution or big-bangism.
.
They've tried to make a joke of it with "Which came first, the chicken or the egg?"
Well, according to Scripture, chickens as well as all other animals, were created mature, chickens laying eggs, and eggs hatching.
The creation of the world from nothing, "ex nihilo," is a dogma of the Faith, and in stark opposition to big-bangism.
.
If you ask big-bang believers about the universe at the time of the so-called big bang, they have a very interesting answer.
This isn't front page news, but it's what they believe.
And it gives us a great clue to how they think and why they have so many problems with how the world began.
They say at the first instant of the big bang, all the KNOWN universe was contained in a point the size of a proton.
Key word, KNOWN. (But they don't use all caps like I do!) 
It was the KNOWN universe for the following reason:
All of space-time was contained in that proton-sized speck, they say.
Consequently, OUTSIDE of that speck, whatever there was we cannot KNOW because it was not the KNOWN universe.
That doesn't mean there was nothing outside the speck!
It only means that whatever it was, it cannot be KNOWN.
.
I'd like to pause for a commercial break.
In ancient Greece there was a philosopher who left no writings.
But one of his teachings comes down to us in one pithy doctrine.
He said that there is but one great heresy, and it has three parts.
I. ---- There Is No Truth.
II. --- Even If There Were Truth, The Truth Cannot Be Known.
III. -- Even If The Truth Could Be Known, It Cannot Be Communicated.
In its simplicity, it covers a multitude of false doctrines which all fit neatly inside of it.
Kind of like the primordial speck, so to speak!
And from the Catholic perspective, it is reminiscent of the Blessed Trinity:  I. The Father, II. The Son, III. The Holy Ghost
In a backwards sort of way, that is, denial of the Blessed Trinity as the great heresy.
.
Getting back to big-bangism, the unknowable OUTSIDE that first proton-sized speck is the subject of much speculation.
Actually, it has so far spawned the idea of the multiverse, dark matter, dark energy, and who knows what else!
For as the BANG occurred (how or why isn't somehow important) all of space-time EXPANDED at an astonishing rate.
Nobody knows if the speed of expansion exceeded the speed of light;  perhaps it did not, or, perhaps it did, somehow.
But in any case, as space-time grew vastly larger, it pushed away at its extremity whatever-it-was that had been OUTSIDE.
As things eventually settled down, the speed of light came to define the limits of the observable universe.
That is, from inside the KNOWN universe, anyone who tries to look to the furthest extent of the universe will be limited.
They will only be able to see as far as the limit set by the KNOWN universe's outer extremity.
For it takes light time to reach us, wherever we are, and if we try to look beyond that extremity, the speed of the light we are looking at means the light has taken as long to reach us as the age of the KNOWN universe, therefore, what lies beyond is UNKNOWABLE.
.
If they were to take this to its logical extreme, they would say, "Even if it could be known, it could not be communicated."
The ancient Greeks effectively had this figured out already.

Big Bang and globe earth are part of the evolutionary and revolutionary pagan religion foisted on us by NASA and idiot scientists like Copernicus, Newton, Kepler and Einstein.   

.
Typo -- should have had St. Joseph's Hospital, Burbank, Calif., not "St. John's" -- that's in Santa Monica. Wrong hospital.

The globe Earth was around a long long time before NASA ever showed up.  Even lying NASA like a broken clock can tell the truth twice a day.

This is very true.  We also know that pagan lying NASA continues to promote evil lies against the Church and Scripture.  A known liar, with the same goals as known liars should never be trusted.  NASA needs to prove earth is a spinning ball, that man went to the moon in 69, that lunar vehicles landed on Mars, that the Big Bang is a viable theory, that earth curves commensurate with a 25,000 mile ball, that CGI photos of a spherical earth are legit and that evolution is true science.  NASA can do nothing of the kind and continues to promote false notions of creation to suit their evolution godless Big Bang.
