I think this is by far the safest and best plan.

Who says that? What is the source?

It a natural renewable sorse.........
Problem is, the "creation" of oil is a lot slower than the current use, and whatever we're using now were created over the period of many million years.

Evidence please.

Not all hydrocarbons have the same percentage of carbon to hydrogen and that is significant. Coal is mosly carbon, so it produces the most CO2 by far, even when compared to oil. Natural gas (methane, CH4) is mostly hydrogen and produces the least CO2.

Well, that is certainly true; however, fuels should be compared to their equivalents, i.e. diesel to a diesel made from coal, and in that case CO2 emissions shouldn't be significantly different. As a matter of fact, if anything, the coal based fuel could be a tiny bit better since it may not have as much aromatics as crude based fuels.

Another thing is -- energy content. To get the same amount of energy one would need to burn more methane than, say, diesel, and that would increase CO2 emission somewhat.
