Yes, it is real: a wooden structure of 476,000 years old built by humans was discovered in Zambia, Africa.

A very old wood structure, found in the depths of the riverbank, could be the oldest wood construction ever discovered. Through a new method of dating by luminescence, scientists discovered that our ancestors built it about 476,000 years ago. The structure consists of two trunks united by a carved notch, long before the existence of modern humans.
Archaeologists discovered old wooden trunks in Kalambo, Zambia cataracts. The trunks were well preserved thanks to the humidity that prevented them from rotting, and the water minerals that made it more resistant over time.

The trunks had intentional marks, probably made with stone tools, and their design suggests that they were used to build something, such as a catwalk, a bridge or the base of a house.
To determine the age of the trunks, the scientists used a dating method that measures the time that minerals were buried in the surrounding land. These minerals, especially feldspar, store radiation as a battery. In the laboratory, scientists release the energy stored to determine how long it has spent since the last time the earth saw sunlight. The results showed that the trunks are approximately 476,000 years old.
The discovery surprises, since most archaeologists thought that these first hominids were nomads. Most of the artifacts of their time, such as spears and sticks to dig, were easy to transport.
But the first humans were apparently less nomadic and more capable of what was believed.
