TONIGHT'S MUST-SEE

MLB All-Star game, 2 p.m. ET, Fox. Yankee Stadium has seen some of baseball's great moments and great players. Now — with a new stadium being finished — it gets one final All-Star game. These games bring lots of emotion and ceremony (especially tonight), plus a tad of importance: The winning league gets home-field advantage (and its rules, with or without a designated hitter) in four of the seven World Series games. Lately, that's been easy to predict: The National League hasn't won since 1996; it did, however, manage one tie.

TONIGHT'S ALTERNATIVE

"Must Love Kids," 9 p.m., TLC. Here's a dating show with a difference: We meet three single moms, each sifting through several guys. Kristin has three children, Vanessa has two. Tracy has only one, but she's a blur of a 5-year-old redhead who seems like a dozen. Each mom is in her 30s, with a day job (patent agent, massage therapist, etc.) that keeps her busy. Each seems to have a playful approach to kids. Now each begins a search for the right guy.

OF NOTE

"Earth: The Biography" conclusion, 4 p.m. National Geographic Channel. This is a terrific, five-hour series. (For proof of that, check the reruns on volcanoes at 3 p.m. and ice at 5 p.m.) Now comes a finale that takes a fresh approach: "Rare Planet" suggests that the Earth might really be unique in the universe. It views all the remarkable forces that worked just right to let complex creatures live here.

"NCIS," 7 p.m., CBS. When a crypt is opened, various body parts are discovered. Now the team searches for a serial killer.

"Celebrity Family Feud," 7 p.m., NBC. Two guys from the "Blue Collar Comedy Tour" — Bill Engvall and Larry the Cable Guy — bring their families for a face-off. Also, it's Vivica Fox against Mo'Nique.

"Secret Life of the American Teenager," 8 p.m., ABC Family. Amy still hasn't told her parents she's pregnant. Tonight, however, she tells her sister. She also grows closer to Ben, a sweet guy who isn't the father.

"America's Got Talent" (NBC) and "Big Brother" (CBS), both 8 p.m. Two popular summer shows collide — on All-Star night, no less.

"POV: The Last Conquistador," 10 p.m., PBS. The idea seemed bold and ambitious: To celebrate its Hispanic roots, El Paso, Texas, hired sculptor John Houser to create an epic statue of Juan de Onate. Then came the protests: This man and his Spanish soldiers had charged through the native villages. They killed most of the people, enslaved others. In a gesture toward "leniency," de Onate ordered that some merely have one foot chopped off. This would be a statue to a terrorist, American Indians complained. This even-handed documentary finds sympathy for both sides and shows a human dilemma that allows no happy ending.
