He was unable to prove his theory because he didn't have any proof.
In short, I believe Darwin's theory was controversial in the 1800s because it contradicted the biblical view of creation.

Prophet Muhammad's (Peace be upon him) march had a great deal of an impact on Makkah. Some people of Makkah, didn't believe in one god, and hurt Prophet Muhammad (Peace be upon him) and his Sahbah (companions). But they didn't give up, and kept preaching Islam, even though the Quershay would hurt them so much, they would throw rocks on them while they were Praying, yet they didn't give up! Some people became Muslim's, and this was the Impact!
General Braddock! Have a good day/night
