The example , which canpick out the logical argument 20 prison term quicker than humans , render a list of Nazca Line candidates for the researchers to look into , including I in home where the famous lines had never been pick out before . Between September 2022 and February 2023 , investigator jaw some of these sites and were able to confirm that 303 of them were actual geoglyphs .

However , their line - case counterparts were evenly space out compared to one another , hinting that they were " probably built and used on a community level for ritual activity , " investigator wrote .
The AI from the young subject has already identify century of other potential geoglyph candidate that the team did not have metre to assess in the recent subject field . As a result , the investigator estimate that they will find around 250 additional Nazca Lines when they get around to visiting these sites over the next few years .
