it appears that you are making the common mistake of attempting to 'inject' God into the scientific and natural formula.
in nature, chaos can reign supreme, especially when we have absolutely ZERO control over events (such as tsunamis, tornadoes, earthquakes, floods, etc...) when these events ocur, we see planet Earth going through a cause and effect due to temperatures, gravity etc.
anything living that gets caught in these 'disasters' is obviously unfortunate.
in nature, living things are born and die, some can live a long time, others not. some will die of disease, others will get eaten, and others will be plainly murdered (pest control) or (gang violence).
man attempts to explain these things with a concept known as God. God attempts to fullfill this ancient and well known phrase,
ordo ab chao - out of chaos, order
but for this to happen, you need an incredible amount of faith.
