2005 Hyundai Tucson wont start but lights are on the dash?

What is your question?

Lights are on the dash, but it won't turn on. There's no ticking at all, the day before it stop working it seemed that the alternator was going out because everything was flickering but i just bought a new battery and the negative cable is loose to point i can twist it off and on. My car stopped in traffic and wouldn't start until i got out twisted the cable and it started back up. But the next day nothing happened not even with a jump. Is it the STARTER, ALTERNATOR or something else.. Help

What makes this problem better or worse?

Nothing its just dead with lights on dash.
