1400 years ago people knew about Earth, sun and the moon. But nobody knew that there were planets outside our Solar System. Today we know that this is false; astronomers found many exoplanets.
When scientists search for life on exoplanets they only look for planets with water; no water no life.
Water Discovered in the Atmosphere of an Exoplanet in the Habitable zone. It Might Be RainWater Discovered in the Atmosphere of an Exoplanet in the Habitable zone. It Might Be RainAstronomers using the Hubble space telescope have discovered water in the atmosphere of an exoplanet in its star's habitable zone. If confirmed, it will be the first time we've detected water-a critical ingredient for life as we know it-on an exoplanet. The water was detected as vapour in the atmosphere, but the temperature of the planet means it could sustain liquid water on its surface, if it's rocky. The planet is called K2-18b, and it's about 110 light years away. The planet is much different than Earth. It's a Super-Earth, and it's twice as large as Earth, and about 8 times as massive. K2-18b is orbiting a red dwarf star, and it was first discovered in 2015 by the Kepler Space Telescope.
An exoplanet was found in the habitable zone with water. However this was portrayed in the Quran 1400 years before it was discovered.
٣٠ أَوَلَمْ يَرَ الَّذِينَ كَفَرُوا أَنَّ السَّمَاوَاتِ وَالْأَرْضَ كَانَتَا رَتْقًا فَفَتَقْنَاهُمَا ۖ وَجَعَلْنَا مِنَ الْمَاءِ كُلَّ شَيْءٍ حَيٍّ ۖ أَفَلَا يُؤْمِنُونَ
In the Quran all life, on Earth and in the Heavens, depend on water. In another verse the seven Heavens are of different types and each has its own planets like Earth:
١٢ اللَّهُ الَّذِي خَلَقَ سَبْعَ سَمَاوَاتٍ وَمِنَ الْأَرْضِ مِثْلَهُنَّ يَتَنَزَّلُ الْأَمْرُ بَيْنَهُنَّ لِتَعْلَمُوا أَنَّ اللَّهَ عَلَىٰ كُلِّ شَيْءٍ قَدِيرٌ وَأَنَّ اللَّهَ قَدْ أَحَاطَ بِكُلِّ شَيْءٍ عِلْمًا
The seven heavens have planets like Earth. Today astronomers found exoplanets like Earth.
How could an illiterate man who lived 1400 years ago have known about exoplanets?
The Quran (Koran, the book of Islam) contains scientific knowledge that could not have been known 1400 years ago. It ranges from basic arithmetics to the most advanced topics in astrophysics. You are invited to go through those miracles and judge for yourself.
