I will answer in the best way I know how:-x

Where exactly are you starting time-wise, (in years ago)?

As far as I understand, you and others or talking big bang (Theory or not?) Many stating that was the start of everything universe and earth and mankind. Mankind, many believe to be as a result of evolution kickstarted by the big bang.

So I am saying, time itself goes way way before that, no length "of" can be known or quoted by anyone of mankind.

Where does God stand with the end of the Earth?

God has never stated the earth will end, He promises mankind everlasting life on the earth so it will never end.

The Earth will end when the Sun gradually runs out of fuel, expands and roasts the Earth to a cinder.

If God promised everlasting life to people on this planet then all that sustains this planet, they the sun the moon stars etc will never cease either.

The planet earth was made with an eco system able to sustain it forever. The same too with the universe.

Mankind was also made with the ability to keep living forever, although I can understand why many would not be able to comprehend that.

As God is the creator of the heavens and the earth he is the one that will keep them in existance forever.

As I said back in my other post.

God has always been in existance he has had no begining and will have no end. He has always been there.

It is absolutley impossible to disprove that.  What I can say is that he has given us much information, knowledge, facts, explanations, prophesies and eye witness accounts in his word the Bible to help us understand and prove to ourselves that he does exist, and he is the creator of all things.

It is up to us what we do with that information and what we decide is true or not. It is fact that there is a God whether we believe it or not doesn't change that.

Of course that is the conclusion I and many others have come to after looking into the bible. We cannot make people believe in anything they do not want to believe in.
