    An important note from the board before submitting your request:
    At LTO, our mission is to interest people, particularly children, in the sciences, using astronomy as a teaching tool. To this end, our materials and presentations approach astronomical phenomena such as the creation of the universe, star formation, planetary formation (including earth) and the size and scope of the universe, from a scientific perspective. While we respect the rights of our guests to hold their own views on such matters, we do not tailor programs to conform to any views other than current scientific thinking.
