The temples built were by hindu empires like the vijayanagara empire or the marathas later who ruled significant parts of India coinciding with the turkic invasion and occupation that you are conveniently not taught in schools. The trukuc invasion left behind a trail of destroyed temples and coties. From sun temple of multan to martand temple in kashmir to ayodhya to mathura to kashi to hampi to belur and halebidu.. its literally a trail of ruins left behind. I dont even know why you are trying to argue that turkic occupation of India was somehow good for natives. The lack of pioneering art, science, technology, philosophy, astronomy, mathematics and literature during this period shows that ordinary people were just trying to survive and could not produce any of these works. Almost all of those great works were before 1000 ad.
