What if we were able to reach a planet that sustains life? A planet like ours, yet slightly different. If it comes to intergalactic travel and contact with other species from other worlds. I'm more a nuts'n'bolts type believer. I believe in technologies we have yet to discover that our ancestors purposely did not leave behind. Simply because I think we are an alien ant-farm gone wrong. That doesn't mean we are limited to the things we can achieve. We are however still very far away before we are able to reach the stars.
This documentary has been around for quite some time. But it's one I find highly interesting. Though I'm afraid I won't live to see this form of exploration. I really love to think about it and fantasise about it like they did in this documentary.
