They claim that but they have no proof alhamdulillah, its all based on faith as they themself say. All them diagrams and pictures they make aren't based on proof or evidence with true fossils or anything like that:
The Propaganda Method Of Evolutionists
The absence of fossils to support the theory of evolution causes evolutionists to resort to window-dressing. They draw totally imaginary creatures that have never existed and use these illustrations as a propaganda tool. There is no fossil record indicating that the half-man half-ape creatures in these drawings ever existed. These drawings are intended to mislead people who have limited knowledge on the subject.
We have divine revelation so we're proud that we're special in the sight of Allaah and not basically animals, because when they say we're mere animals - all they simply want to do is make us seem cheap so people don't fear to eradicate others - because their claim of 'survival of the fittest' will be a good excuse for them.
We're created for a much greater purpose, and that is to submit to our Creator and Sustainer, the Most Merciful - and He is Most Appreciative of that.
And (remember) when your Lord proclaimed: "If you give thanks (by accepting Faith and worshipping none but Allâh), I will give you more (of My Blessings), but if you are thankless (i.e. disbelievers), verily! My Punishment is indeed severe." [Qur'an 14: 7]
Anyway we won't stray off the topic now insha Allaah.
