Take Saturn, for example, with its series of rings and satellites, its immense distance from the sun, 886,000,000 miles, moving at the rate of 22,000 miles per hour, and having a year equal to about 30 years of our globe. He flourishes at a distance from us of about 300,000,000 miles. He has a diameter of 73,000 miles. His volume is 700 times that of the earth, and he receives his light from the sun, just the same as we do. It is admitted by astronomers that the Saturnal scenery is most magnificent, and surpasses anything we are familiar with. The rings form immense arches, which span the sky and shed a soft radiance around; while in the strange beauty of the night eight moons in all their different phases, full, new crescent, or gibbous, light up the starry vault. We know that the planets are composed of the same elementary substances as this world whereon we live, that they are also surrounded with an atmosphere, have water upon them, receive the sun's heat, exhibit all the peculiar characteristics of this globe of ours, and all the planets seem to be obeying the same general universal laws. Can anyone give us a plausible reason why there is no organized vital matter on our neighboring planets--plants, living creatures, similar to those found on this terrestrial globe? If the elementary substances are the same as those that are found on this earth, and they have a similar sunshine, heat, moisture, and temperature, all the forces may be presumed to be the same or similar. There is no reason that the elements should not enter into organic life of a similar, perhaps either inferior or superior, organization to that existing on this world? What is to hinder them? It is certainly possible, therefore probable. May we not assume that it is both possible and probable? Those on earth who believe that this globe of ours was especially fitted up for us, made for man only, are very presumptuous. There was no special forethought for the adaptation or convenience of creatures like ourselves. As to the forethought, adaptation, or convenience, the hog, the elephant, the ass, and the fly enjoy their life just as much as men do. It is very convenient for them. But not more so than it is for man, and it is no more convenient for man than it is for the animals. We are certainly nearer the truth to say that the other planets are inhabited by beings, races, that may exhibit as much intelligence as, if not more than, we do on this globe. The conditions of light and heat may not be the same. The other planets may vary in form and structure, and have shapes not at all familiar to us. That, however, does not in any way interfere with the reasonable probability, nay, certainty, that they are inhabited.
