Atheists, can you please answer these questions..?

I don't think that 3 has been adequately addressed yet, so I'll take a stab at it. The thing that this argument neglects is the key to modern evolution, natural selection. It's a ulative process that gradually builds things up through more and more viable intermediates. The process takes time and is more than just random chance. To adapt your ogy to this, I'll use a tornado instead of an explosion since explosions are generally interpreted as a single event rather than an ongoing process. Also, to account for the fact that the intermediate stages are more viable than the starting material, you'd have to say that when words do end up in the right order, they stick that way. While the one-time event is ridiculously improbable, it is conceivable that, with enough time, a complete dictionary could be embled by this ulative technique.
