At the debate several years back, Steve asked how multi-celled organisms could have evolved. I gave a quick answer there on the spot but recently got around to doing a proper animation on the subject. Here it is:

In the video description on YouTube you can find links to all the experiments.
How did multi-celled animals evolve?
Re: How did multi-celled animals evolve?
Perhaps a more challenging question is, "What is the origin of the first forms of life—supposedly single-cell organisms? Did they simply appear out of nowhere? Or were they brought here by ancient visitors from other planets or systems or galaxies? The latter doesn't really explain anything; it just moves the problem a step backwards.

Man judges a person by his past deeds, and administers penalties for his wrongdoing. God judges a person by his present character, and disciplines him that he may become righteous.

Current thinking is that the first life forms would have been free living genes made of RNA or something similar to it.
I have a video explaining why that idea is most probable given our current understanding of life and chemistry right here: https://youtu.be/K1xnYFCZ9Yg
