Soft Tissue in Fossils—Totally Compatible with Millions of Years?

In 2005, scientist Dr. Mary Schweitzer and her team found unfossilized soft tissue in a T. rex femur—red blood cells, blood vessels, and collagen fibers. It was a phenomenal find, and since then, soft tissue has been found in many other fossils (some considered to be hundreds of millions of years old by evolutionary dating). Soft tissue is a tremendous confirmation of the biblical timeline of just thousands of years for fossils . . . or is it?

In 2016, the old-earth creation organization Reasons to Believe published a book called Dinosaur Blood and the Age of the Earth. The book attempts to harmonize the existence of soft tissue with the millions of years worldview and discredit young-earth creation arguments regarding these soft tissues. A decade later, this book continues to be promoted. So what do we make of these arguments?

Well, AiG geologist and former director of research, Dr. Andrew Snelling, is writing a six-part series, thoroughly reviewing Dinosaur Blood and the Age of the Earth and responding to the claims. The subtitle of the first installment in the series gives you an idea of what Dr. Snelling will be exposing in his response: “Part 1—Dinosaur Blood and the Age of the Earth: A Futile, Deceitful Attempt to Critique Valid, Powerful Young-Earth Evidence.”

The short answer is, no, soft tissue is not compatible with an old earth, and yes, it is indeed a powerful confirmation of the biblical timeline.

The short answer is, no, soft tissue is not compatible with an old earth, and yes, it is indeed a powerful confirmation of the biblical timeline. For all the details, I encourage you to read Dr. Snelling’s thorough series, starting with Part 1. The whole series will be posted under “Review of Dinosaur Blood and the Age of the Earth” as each article is published. Be sure to bookmark that page and check back so you don’t miss any of the articles. I consider Dr. Snelling the leading creationist geologist in the world.

Reasons to Believe, and other compromising ministries like it, promote an old earth because they chose to start with man’s ideas about the past rather than God’s Word. They may say they believe God’s Word is the authority, but they reinterpret God’s Word in light of man’s ideas. God’s Word isn’t really their authority—sinful, fallible man’s interpretations of the past become the authority. That’s why this issue matters so much—it all comes down to biblical authority!

Science, including soft tissue in fossils, confirms the Bible, not old earth and evolutionary ideas. We can trust God’s Word!

Thanks for stopping by and thanks for praying,
