This question gets asked again and again, if you check out other threads in this section, you'll find a loads of reply on the same subject.
Basically you either have to offer goods/services to get BTC, If you have some skills you can open a thread in the
Services section and mention things you're good at like Writing, Programming, Online Marketing and someone might hire you. Or you can sell products for BTC in
Marketplace.
Other than that you can take a look at
Micro earnings section and you'll find lots of faucets, GPT, PTC sites that you can collect free satoshis from and there is
Gambling &
Games and rounds section, where you'll find giveaways offered by various gambling sites and most of the gambling sites have faucets so you can play with them and maybe you'll get lucky.
And there are also
Signature Campaigns, where you can earn money based on your Rank and the Quality posts you make by putting a company's advertisement in your signature. But very few of them accept Newbies but you can check it out and see if you can find one. GL
