Question #1 this is one for theoretical physiatrists. I have, however, heard that the universe came from a singularity and thus not from nothing.
Question #2 RNA, DNA and assorted proteins, etc. See: INTRODUCTION TO CELL REPRODUCTION
Question #3 The Origin of Life
Question #4 The underlying supposition is entirely false. In those instances where older fossil containing strata are found on top of younger faulting and bending are in evidence as well. Thrust faults at plate edges are particularly clear indications. Overall, there is no geological evidence for a great, worldwide flood.
Question #5 A Live Science article "Controversial T. Rex Soft Tissue Find Finally Explained" covers this one.
I meant no disrespect for you as an excellent FReeper but I have no respect for the sources you seem to be getting your questions and information from. I believe they are making a lot of money out of distorting science and in some cases outright lies.
It may surprise you to learn that a global flood is a very common, widespread misunderstanding of the Bible. It was "worldwide" only in that it occurred throughout the existing "world" of men, who had restricted themselves to a small region of earth, in defiance of God's command to fill the earth. This limited understanding of "worldwide" has complete scriptural support in both Old and New Testaments.
Any form of life, or specifically life as we know it?
