Absolutely. With as large as the universe is why wouldn't there be life on other planets and why would they not explore the universe as we re trying to do within our own galaxy. We are but infants in this stage of evolution and much of our technology has only occurred within the past 100 years. Our last space exploration involved a trip to the moon which occurred in the latter 60's and the only thing of note is a space station and a bunch of satellites for communications, television, security, etc. We will need better forms of propulsion to get further out and we will need ways of countering the aging process from such extended space travel, etc. At present we cannot even solve many of our own aging infrastructure issues so we have work ahead of us.
