Humanity is not ready for the next age: the space age
Over the centuries we have known different ages: prehistoric times, stone age, bronze age, middle ages, industrial revolution, technological evolution and the next evolution is the space age so exploring the space and thus also the planets but for this humanity is not ready because we have been for centuries warfare. Last century: WW1, WW2, vietnam, Cold war, iraq, Afghanistan, ..)
The creator (God) will not allow us to go to the space age because we'll destroy other civilizations on other planets.
Technological evolution brought with it a spiritual devolution (no longer believing in God). We reduced ourselves back to the level of the animals. Example is of the lion that encounters a lioness with cubs and the lion will kill the cubs to meet the sexual need => empathless.
