Cosmological theory is a scientific theory . (It should be noted that a scientific theory differs greatly from common notions of what a theory is) . A cosmological theory takes scientific facts, raw data, evidence & logical argumentation & organizes it as an explanation of the cosmos ... The "argument" is purely philosophical in nature. It's origins are widely attributed a Muslim named Kalam in the Middle Ages. It sought to use the workings of the cosmos as a proof for the existence of a god. It positions a god as a kind of "first mover". However; the argument is weak & has been refuted on many levels. It's based on a misunderstanding of "cause & effect".
It is difficult to determine. Some of the earliest accounts of scientific inquiries go back at least as far as the middle of the 1800s. It is possible that scientific accounts were made before them that have been lost or have been hidden in some obscure corner of a library for the past century. Perhaps the earliest account of a tornado from an actual scientist was one by John James Audubon, of a tornado near the Illinois/Indiana line in 1814. However, Audubon primarily studied birds and was merely present to witness the tornado. A man named James Espy appears to have conducted some study of tornadoes at least as early as 1840. By that time he had developed a hypothesis about tornadoes, which was later proven wrong. The person who may be regarded as the father of the study of tornadoes is John Park Finley, who began his research in 1879.
