Another reason why astronomers and astronauts should devote most of their resources to exploring Mars is to find extraterrestrial creatures. Scientists can extend their knowledge of the cosmos by learning from extraterrestrial creatures, (if they find any.) For example, the extraterrestrial creatures may know as much about their area in space as well as we know about our place in the cosmos. The extraterrestrial scientists and our scientists could have a conversation, thereby stretching their and our theories and knowledge about the universe. Also, the extraterrestrial scientists and our scientists could work together to gather even more information about space.
Finally, scientists will invent and improve upon technologies while they are working on exploring Mars. For example, the people living on Mars might discover something there that might help Earth a lot. Also, extraterrestrial creatures might have important technology tips to share with us. We might improve medical technologies through our space exploration so less people will have serious illnesses or injuries. After working in space, doctors may become more efficient too.
Some people might not feel that is is worth exploring Mars because it will take a lot of money. Although this is true, the discovery of extraterrestrial creatures will really improve Earth. It will make our everyday lives better. Also, Mars is in tip-top shape for terraforming.
I strongly believe astronomers should spend most of their time, energy, and money trying to make Mars a place that is possible for people to live on and trying to find extraterrestrial creatures. Living on Mars and meeting new friends; a wondrous dream that can possibly be made into reality if we work hard enough!
