I think that it would be an intelligent idea to set foot on Mars. Why? Well for one, we need to know that if under the worst possible circumstances, we have a backup plan. We need to know that Mars is safe and capable of holding life. If something ever does happen to Earth, then we need to know that we'll be safe somewhere else. There has already been discussion of sending a couple of people to Mars to live there, and I think this will happen. I do agree that setting foot on Mars is a clever idea, because know we will know for sure if Mars could be another life-containing planet. If we never set foot on Mars, these answers will never get resolved.

I agree that dogs are much better than cats. You can do multiple different activities with dogs, but most cats that I have seen like to be alone. I also find that dogs are much more of a child and family pet. They are cuddly and can be well-trained if you wish them to be.

I, for one, do believe in God. There are too many events that have happened and will happen that science can not explain. The universe did not come to be by chance. God is a way for people to explain all these events. Even though, we can not do experiments to show of God's existence or put him in a test tube or some sort of scientific method, that does not mean we should say that "God does not exist!"
