Not for creationism or anything, I just think people lack perspective.
Potholer54's "Made Easy" series on Youtube does an excellent job of explaining everything the origins of stars, planets, life, and the evolution of life:
In regards to showing the intelligence of other animals, here are some good videos about gorillas, chimps, and bonobos:
I have found that if someone believes that there is a god that created the whole world, then they do not value scientific data as proof of or disproof of anything. They believe what makes them feel good. So, instead of trying to help them understand the truth behind science, you need to stress the results of science and how they have changed that person's life as well as how science has changed society's standard of living. If you are a fair person or a detailed type person, you may feel the need to include the bad in with the good that science has done, but that would not follow the religious methods that trained that person to believe in a god that created the world.
Have a great day!
In an attempt to resubscribe me to their magazine, Skeptic Scociety sent me a very nice little
booklet titled "Top 10 Myths About Evolution".
It's a 4 x 4'' foldout, well written, and very concise and readable to the theist or person who knows nothing about the subject.
Each myth is answered in a few short paragraphs, so great quick reading for someone who wants to hear the answer, but does not want to get their faith "dirty" by investigating details,
for fear of having some of Satan's EVILution contaminate their soul :)
I was going to through it away, but my christian cousin once asked me about evolution (after first being shocked that I actually believed it), so I will give it to her.
I am sure if you go to their webpage, you can find it.
