According to Genesis, the first men were even building cities, inventing musical instruments, crafting in bronze and iron, and keeping calendars. Calendars are among the very earliest forms of writing found by archaeologists today.
The Bible's picture of advanced, intelligent and ever-curious man is further supported by the discovery all over the world of ancient observatories. Some of these observatories, such as Stonehenge, are so ancient that little is known about the builders. In fact, when many of the structures which are now known to be observatories were first discovered, no one could figure out the purpose of these structures. Several years ago, 60 additional observatories were positively identified in the American Southwest. The first, and most famous, is the so-called "sun dagger" in New Mexico. Two spiral designs had been cut into the rock so that a shaft of light, passing through nearby rocks, would illuminate key portions of the carvings only on solstices and equinoxes.
The creation itself declares the glory of the Creator. Man's own activities provide a strong witness to the fact that the Bible's story of the special creation of intelligent, inquisitive man is completely reliable.
