The first animal "death" we see in the bible is immediately after sin. I do not see any indication that there was one before that.
This is true, but your argument is also made from silence.
I personally believe that the fossil record of the Grand Canyon (and Carnarvon Gorge here in Australia) demonstrates that the sediment was built up over a long period of time in a period before the flood, and before land animals were made.
I think each creative day took 1000 years each, as 2 Peter 3:8 says: “that one day is with the Lord as a thousand years, and a thousand years as one day.”
Although God says he made the heavens and the earth in the 6 days; God also says that He made them in 1 day. (Genesis 2:1) This is a flag (for me) to understand the days as not being 24 hour days.
I arrive at this conclusion also by noticing that there are hundreds of meters of sediment found in the Grand Canyon that was formed under water; but not by the great flood of Noah’s time. The sediment was formed under water because of the limestone deposits are formed under water. Much of America (and Australia) was under water, covered by a shallow inland sea sometime in the past. This is understood by noticing the types of fossils that are found in the sediment… They are ALL fossils that come from a shallow sea. There are NO land animal fossils in hundreds of meters of sediment; which you would expect to find if the sediment was deposited by the flood of Noah.
So these hundreds of meters of marine animals found in the sediment give the idea that sometime in the past, before the flood, there were long periods of time where marine animals existed, but not land animals. These marine animals, millions of them, are deposited in hundreds of meters of sediment. The first land animal fossils appear close to the top of the Canyon as footprints.
I study Geology, so I am exposed to this information. Geologists claim that this sediment was deposited over millions of years; which I reject. Creationists claim that the sediment was either deposited in one day, before the flood, or in 1 year, during the flood. I do not think either of these theories fit the data…
If the sediment and fossils was deposited in one day (as in a creation day); then there must have been an enormous catastrophe affecting only marine animals; and if the sediment and fossils were deposited in one year (as in the flood), then why are there no land animals found in the sediment? The other alternative is to say that marine animals and plants died in a thousand year period. There were catastrophes in these creative days, such as earthquakes, volcanoes and tsunamis, for these were instruments that God used to form the earth. God made the earth with oil, gas and coal deposits in perpetration of these very days. These things did not get here by accident, they were planned by God. These end-times were planned…, because God was not deceived by Satan, man was. God knew that Satan would foil mankind; and God made the earth with redemption already planned.
God “predestined us in Him before the foundation of the world”. How could God predestine us in Him (Jesus) before the foundation of the world unless God knew? God's plan of Jesus was determined even before the world was founded.
Will there be animals in heaven? No. Will there be animals on the new earth? Yes
God Bless
