This most beautiful system of the sun planets and comets could only proceed from the counsel and dominion of an intelligent and powerful Being. And if the fixed stars are the centres of other like systems these being formed by the like wise counsel must be all subject to the dominion of One; especially since the light of the fixed stars is of the same nature with the light of the sun. ~ Isaac Newton 1642 to 1727
It is thus probable that germs of the lowest organisms known to us are continually being carried away from the earth and the other planets upon which they exist.

Yet a small number of spores will fall on some other world and may there be able to spread life if conditions be suitable. ~ Svante Arrhenius 1859 to 1927 - Physical Chemist
