What Was The “Pitch” For Noah’s Ark?

What Was The “Pitch” For Noah’s Ark?

The Bible comes under attack in many different ways. Even details that most people would consider mundane often become the focus of skeptical criticism. One such detail is found in God's instructions to Noah regarding the construction of the Ark:

"Make yourself an ark of gopherwood; make rooms in the ark, and cover it inside and outside with pitch." (Genesis 6:14, NKJV)

Discussions often arise over the meaning of gopherwood or the design of the "rooms" (or compartments) within the Ark (which is discussed in the book A Flood of Evidence). In this article, however, we will focus on another alleged problem—the use of pitch.

What Is Pitch?

To understand the criticism, it helps to know what pitch actually is.

Pitch is a thick, sticky substance used to waterproof wood and other materials. It seals cracks, prevents water from penetrating the wood, and greatly increases the longevity of wooden structures. For a massive vessel like Noah's Ark, pitch would have been an ideal waterproofing agent, helping to keep the Ark sealed and free from leaks during its year-long voyage (Genesis 7:11; 8:14).

Today, most commercial pitch is derived from petroleum products. Because petroleum is abundant and inexpensive, it has become the primary modern source for making many waterproofing materials.

The Alleged "Gotcha" Moment

So why do some skeptics attack pitch for Noah’s Ark?

Many creationists have pointed out that most oil and petroleum was formed as a result of the Flood of Noah’s Day. Crude oil for example is the remains of biologicals (trees, plants, algae, animals, etc.) that seeped out of what-became-fossils and pooled together into subterranean areas.

Massive quantities of buried plants, algae, trees, and animals were rapidly entombed under sediments. The heat and pressure from the Flood transformed much of this organic material into petroleum deposits.

Skeptics then ask what they believe is a "gotcha" question and it goes something like this:

"If petroleum products were formed during the Flood, where did Noah get pitch before the Flood began?"

At first glance, some people think this sounds like a serious objection. But the argument assumes something that simply isn’t true. It assumes that petroleum is the only source of pitch.

The Solution

The answer is actually quite straightforward. Although much of today's commercial pitch is petroleum-based, petroleum isn’t the only way to produce pitch. Long before the modern petroleum industry existed, people throughout history produced waterproof pitch from tree sap.

Even today, in some remote parts of the world, craftsmen still produce pitch from tree resin or sap. Pine trees and many other resin-producing trees naturally yield sticky substances that can be refined into waterproof coatings. Typically, the resin is heated or boiled to remove impurities and produce a durable, uniform pitch suitable for sealing wood.

This would have been an obvious solution for Noah. Rather than depending on petroleum reserves, Noah had access to enormous quantities of freshly cut timber. Every tree that was harvested for the Ark contained sap and resin. As the trees were felled and processed, large quantities of resin could have been collected and refined into pitch.

Noah, his family, and perhaps hired workers could have manufactured substantial amounts of pitch using the very resources already required to build the Ark. In other words, Noah's building materials also supplied the raw ingredients for waterproofing the Ark.

Was There Enough?

Some may still wonder whether enough tree resin could have been collected.

Consider the sheer scale of the Ark's construction. The Ark Encounter in Kentucky, which is only a modern replica of Noah's Ark, required approximately 1.2 million board feet of timber for its construction. That figure doesn’t even include every log and piece of lumber involved in the overall project.

If a project of that magnitude requires millions of board feet of wood today, imagine the tremendous amount of freshly harvested timber Noah would have processed. Those trees would have contained vast amounts of sap and resin that could be collected during harvesting.

Since God commanded Noah to coat the Ark both inside and outside with pitch (Genesis 6:14), there would have been ample opportunity to gather and refine large quantities of tree resin throughout the construction process.

Furthermore, God gave Noah many decades to complete the Ark (Genesis 6:3; 7:6), allowing plenty of time to produce the pitch needed for such a monumental undertaking.

Final Thoughts

The objection that Noah couldn’t have obtained pitch before the Flood is based on a false assumption fallacy. It incorrectly assumes that all pitch must come from petroleum.

While petroleum-derived pitch is common today, humans have produced pitch from tree resin for thousands of years (and still do in remote areas!). Noah had abundant access to freshly harvested timber, making tree-derived pitch a simple, practical, and readily available waterproofing material.

Rather than presenting a problem for Genesis, this objection actually shows how modern assumptions can be errantly read back into the ancient world. Noah had everything he needed to obey the Lord's command, including the materials necessary to waterproof the Ark. The Ark was the means of salvation from the Flood and God prepared them. Likewise today, an eternal salvation awaits has been sufficiently prepared for those in Christ.
