The only way I know of is carbon dating. Which according to Wikipedia is:
Radiocarbon dating, or carbon dating, is a radiometric dating method that uses the naturally occurring radioisotope carbon-14 (14C) to determine the age of carbonaceous materials up to about 60,000 years. Raw, i.e. uncalibrated, radiocarbon ages are usually reported in radiocarbon years "Before Present" (BP), "Present" being defined as AD 1950. Such raw ages can be calibrated to give calendar dates.
One of the most frequent uses of radiocarbon dating is to estimate the age of organic remains from archaeological sites. When plants fix atmospheric carbon dioxide (CO2) into organic material during photosynthesis they incorporate a quantity of 14C that approximately matches the level of this isotope in the atmosphere (a small difference occurs because of isotope fractionation, but this is corrected after laboratory analysis). After plants die or they are consumed by other organisms (for example, by humans or other animals) the 14C fraction of this organic material declines at a fixed exponential rate due to the radioactive decay of 14C. Comparing the remaining 14C fraction of a sample to that expected from atmospheric 14C allows the age of the sample to be estimated.
The technique of radiocarbon dating was developed by Willard Libby and his colleagues at the University of Chicago in 1949. Emilio Segrè asserted in his autobiography that Enrico Fermi suggested the concept to Libby in a seminar at Chicago that year. Libby estimated that the steady state radioactivity concentration of exchangeable carbon-14 would be about 14 disintegrations per minute (dpm) per gram. In 1960, he was awarded the Nobel Prize in chemistry for this work. He first demonstrated the accuracy of radiocarbon dating by accurately estimating the age of wood from an ancient Egyptian royal barge for which the age was known from historical documents.
Archaeologists typically use several methods to estimate the age of artifacts, such as radiocarbon dating, dendrochronology (tree-ring dating), stratigraphy (examining the layers where artifacts are found), and thermoluminescence dating. By analyzing the materials, context, and surrounding evidence, archaeologists can determine the approximate age of the artifact or findings.
There are a great number of methods which can be used to determine the age of artifacts or fossils. The method used depends on a many factors such as the age of the artifact, the material from which it is made and the conditions which it came from.

All my book says is that they use advanced technology and they make educated guesses. By this i believe they mean that they use relative dating (the placement of a fossil or item in a layer of rock (normally sedimentary) or soil) or another way they may use is by using carbon atoms to find the exact date of the object.
an archaeologist know how old an artifact is by dating it
they carbon date it
carbon dating
Carbon dating can be used by archaeologists to estimate the age of artifacts that contain organic material. By measuring the decay of radioactive carbon isotopes in the artifact, scientists can calculate its age within a certain range. However, carbon dating is not always accurate for very old artifacts, and other dating methods may be used in conjunction with carbon dating for more precise results.
Correlated age in archaeology refers to determining the age of an artifact, site, or event by comparing it to other dated materials or contexts. This helps archaeologists establish a relative chronology for different remains based on their similarities or associations.
The artifact is approximately 17,500 years old. This calculation is based on the half-life of carbon-14, which is about 5,730 years. By determining the percentage of remaining carbon-14 in the artifact, scientists can estimate its age.
Carbon-14 dating is used to determine the age of organic artifacts by measuring the amount of radioactive carbon-14 present in the sample. By comparing the ratio of carbon-14 to carbon-12 in the artifact to the ratio in living organisms, scientists can estimate the age of the artifact based on the rate of carbon-14 decay.
Archaeologists use radiocarbon dating to determine the age of organic artifacts by measuring the decay of radioactive carbon isotopes. Another technique is X-ray fluorescence (XRF) analysis, which helps identify the elemental composition of artifacts, providing insights into how objects were made and traded.

Yes, well, mostly anyway.

Which of these dating methods is capable of giving the most accurate age of an artifact?
Carbon-14 dating is used to determine the age of organic artifacts by measuring the amount of radioactive carbon-14 present in the sample. By comparing the ratio of carbon-14 to carbon-12 in the artifact to the ratio in living organisms, scientists can estimate the age of the artifact based on the rate of carbon-14 decay.

To date an artifact, archaeologists use various methods such as radiocarbon dating, dendrochronology, pottery typology, stratigraphy, and seriation. These techniques help determine the age of the artifact based on its context, material composition, form, and associated finds. Combining multiple dating methods can provide a more accurate estimate of an artifact's age.
There is no specific age requirement for an artifact. Generally, an artifact is considered to be an object created or used by humans that has historical, cultural, or archaeological significance. The age of an artifact can vary depending on the context and discipline in which it is being studied.
There was such little recorded history and archaeological findings.
Archaeologists study past human societies by analyzing artifacts, structures, and other physical remains. They aim to understand the cultural practices, beliefs, and lifestyles of ancient civilizations. Their work involves excavation, data analysis, and interpretation to piece together the story of human history.
