All you did was show me a video of a thing bone. I have a large thigh bone too compaired to a midget.
According to Islam earth predates mankind and was inhabited by another race called Jinni. Ibliis was one of them. Animals and plants populated earth all that time. Most of these ancient animals died off for one reason or another and earth went through cycles of change. If bones are found that show evidence of these pre-human-history large animals, Islam won't deny it. Islam has no objective imposing religious view on it. There is no reason to object to bones found.
What Muslims object to is the make-belief ideas of how these animals including human beings came to be.
