Mishpetei Uziel
Answer: We learn in Tractate Pesachim (54a), "Rabbi Yosei says, 'The thoughts of two phenomena arose in God’s mind on Shabbat eve, but were not actually created until the conclusion of Shabbat. At the conclusion of Shabbat, the Holy One, blessed be He, granted Adam, the first man, creative knowledge similar to divine knowledge, and he brought two rocks and rubbed them against each other, and the first fire emerged from them.'" And in the Yerushalmi (Berakhot 8:5:8), we learn, "Rabbi Levi said, '[At this moment,] the Holy One, blessed be He, let him find two flintstones that he struck against one another and fire emerged from them; that is what is said (Psalms 139:11), "Now the night is light for me," and he recited the blessing upon it, "Who created the lights of the fire."' Shmuel says, 'Therefore we recite the blessing over the fire at the conclusion of Sabbat, since that was the time of its first creation.'"
