Miracles are a thing which is often received with skepticism as we are not in a position to "behold" the miracle before us. They are a thing of the past and for most they are as good as fairy tales.
But one thing we have with us today, thankfully we have something to look at, something that can be "tested"! The Holy Quran.
The Quran has a mathematical miracle which can be easily tested, which is not subject to interpretative judgement. I present an excerpt of the source here:
"The momentous discovery that “19” is the Quran's common denominator became a reality in January 1974, coinciding with Zul-Hijjah 1393 A.H. The Quran was revealed in 13 B.H. (Before Hijrah). This makes the number of years from the revelation of the Quran to the revelation of its miracle 1393 + 13 = 1406 = 19x74. As noted above, the unveiling of the Miracle took place in January 1974. The correlation between 19x74 lunar years and 1974 solar years could not escape notice. This is especially uncanny in view of the fact that “19” is mentioned in Sura 74."

I strongly recommend that the reader should check out the complete detail of what the miracle is exactly about.It might not make sense in the beginning paragraphs so YOU WILL HAVE TO READ FURTHER TO KNOW IT. See link below:
Appendix 1, One of the Great Miracles [74:35]
P.S. When I began reading this for the first time I was myself skeptical of this really being something miraculous. But this seems good enough.
Have a look and the more you read it the better it gets. Also if you have acquaintance with Quran you will appreciate the points better.
