Some thoughts on time travel

I've ashamed to say I've given this quite a lot of thought, and I've devised a few number of reasons why time travel would be impossible, if not highly inconvenient.

• There is a severe risk of causing time paradoxes (You go back in time and kill yourself, therefore causing yourself and everyone you've affected to change).
  
• Let's say you go back two minutes in time, what happens to your body in this moment? Does it just disappear or just stay there as a clone of you?
• God created time as an ever-moving system to govern us. I don't think He really wants us mucking around in it.
