What would be a scientific sign?
What we would typically expect from a book by God, as it claims to
be, is, apart from a moral guidance, is some deep knowledge of the past,
the present and the future. If it is supposed to be scientifically correct,
there should be verses which describe discoveries in areas of research
which are based on a high level of technology, such as statements about
geological, astronomical or biological phenomena in nature. The phenomena
that ought to be described should be known to modern science only since
very recently and only due to the progress that has been made in areas
such as those mentioned above. These could for example be precise descriptions
of the structure of the earth, the different layers and characters of
the atmosphere, maybe even the age of the universe and the earth, the
Big Bang, Evolution of life, or even the precise embryological development
of a child on maybe a microscopic level. There should be much more in
it. And it should be morally beneficial.
And then there is still the question, whether the passages of such
scientific meaning would really be significant and precise enough to
wipe out any doubt about the truth of its source? Are those really signs
of God or could those statements be interpreted differently? Or was
it possible to make discoveries in those times that would have lead
to a good enough knowledge to describe these natural phenomena?
The cultures in the Old World
Well, the fact is that the inhabitants of Arabia at the time when
the Quran came into being were poetically but not at all scientifically
skilled. Only after this revelation enlightened them, they started integrating
the science of many cultures that embraced Islam at that time (see The
Calendar, David Ewing Duncan, Fourth Estate London, 1999). The philosophers
in Greece and Egypt had made many geometrical and mathematical discoveries
but did not possess submarines, echolotes or telescopes. The Chinese
drew maps and sailed across the Pacific but didn't have compasses, satellites
or microscopes. The Indians invented Algebra and the concept of Zero
but had no rockets or aeroplanes in those times. In fact the planetary
view of these peoples alongside the dominating cultures of those times
in the early Middle Ages was very different from the one today. The
Roman Catholic Church laid the very foundations for the suppression
of scientific knowledge during the Renaissance and had a geocentric
view based upon their doctrines. Many scientists and followers of other
religions were killed during the crusades and the inquisition (link

Muslim colleagues in Spain and Persia. This period is remembered as
the Renaissance, the rebirth of ancient philosophy in Europe which had
been preserved and developed by the Muslims. In addition to that, Muslims
had established experimental methods because God commands them to ponder
on every detail of his creation:
"He Who created the seven heavens one above
another; no want of proportion wilt thou see in the Creation of
(Allah) Most Gracious so turn thy vision again: Seest thou any flaw?
Again turn thy vision a second time; (thy) vision will come back
to thee dull and discomfited in a state worn out."
Surah Al-Mulk, 67 Ayah 3/4
Great writings of Socrates and Plato had been preserved by Muslims
who had translated them into Arabic, Persian and Turkish before the
originals were burnt by crusaders and tartars. Later many Muslim books
were translated into Latin by Spanish Muslims in Grenada and Cordoba.

Talents such as Omar Khayyam, Al-Razi, Al-Geber (Algebra), Al-Hazen,
Al-Ghazali, Al-Khuwarizmi (Algorithm) and Ibn-Rushd are only a few from
the multitude of geniuses whom the Muslim world contributed to civilisation
and who were held in honour by Thomas de Aquinus, Francis Bacon, Isaac
Newton, Gallileo Galilei, Leonardo da Vinci and Descartes. These were
all students of Muslim sciences and pioneers of the Renaissance, Age
of Reason and Enlightenment in Europe. An age during which the fundaments
of the Christian churches were shaken by a deep tremor of human awakening.
The Muslim civilisation dominated world-wide as long as its citizens
followed the commandments of Allah (,the only God).
The big challenge
So if the descriptions in the Quran are related to phenomena in nature
which have only been possible to be discovered with the help of devices
and instruments invented recently, then what does that mean for us?
We have to check, whether the statements in the Quran just accidentally
relate to these phenomena ? How many signs are there? Are there enough
to convince us that the Quran is the true word of God? Here's a list
and explanation; you have to judge for yourself about the he following
promise:
"Soon will We show them Our Signs in the (furthest)
regions and in their own souls until it becomes manifest to them that
this (the Quran) is the Truth. Is it not enough that thy Lord doth
witness all things?"
Surah Ha-Mim Surah 41 Ayah 53
Let's start with the furthest regions (the universe) and work our
way to our own souls (the human body)
