Islam true religion?

http://islamic-replies.ucoz.com/2/Quran_...Light.html = Science supports Quran.

As far as I understood, this was the gist of the argument
Muslim says: Mohammad (and therefore quran) correctly predicts the reflective nature of moon which he could not have known unless told by god himself because that knowledge wasn't available to humanity.

Atheist says: The knowledge was available and here is the list of previous astronomers who have said the same thing.

Muslim refutes the argument by saying
1. No evidence that this knowledge reached Mohammad and 2. Certain incorrect concepts were not included.

Consider this:

Aryabhata: 476–550 CE: Indian Astronomer:

Aryabhata was the author of the Āryabhatīya and the Aryabhatasiddhanta, which, according to Hayashi (2008): 'circulated mainly in the northwest of India and, through the Sāsānian dynasty (224–651) of Iran, had a profound influence on the development of Islamic astronomy. Its contents are preserved to some extent in the works of Varahamihira (flourished c. 550), Bhaskara I (flourished c. 629), Brahmagupta (598–c. 665), and others. It is one of the earliest astronomical works to assign the start of each day to midnight.'[4] Aryabhata explicitly mentioned that the earth rotates about its axis, thereby causing what appears to be an apparent westward motion of the stars.[4] Aryabhata also mentioned that reflected sunlight is the cause behind the shining of the moon.[4] Ayrabhata's followers were particularly strong in South India, where his principles of the diurnal rotation of the earth, among others, were followed and a number of secondary works were based on them.[1]

Here we have an astronomer who lived before Mohammad, whose findings were scientific, who had a great following, which means his works well known and the knowledge of whose work is known to extend to the area where Islam developed. To the extent that development of Islamic astronomy relied on the influence.

This evidence supports the hypothesis that the knowledge of moon's reflected light was not only possible but even probable to Mohammad.
