Real History of Red Fort

The so-called anti-Sanatan historians wrote - Red Fort was built by Mughal Shahjahan in 1638 !! But the Oxford Museum is a picture of 1628 in London, meeting the foreign ambassador in the Red Fort in 1628 Shahjahan "crazy mango"!! When Shahjahan started building Red Fort in "1638", how did Shahjahan reach inside in "1628"?? Based on the written evidence, it is clear that the Red Fort was built by King Anangpal Tomar II in the 10th century, whose name was "Lalkot" !! Maharaja Anangpal Tomar II, Emperor Prithviraj Chauhan and Emperor Jayachandra Rathore's grandfather !!
