Do you think it's wise to invest in stock market?

Yes it is, however you don't have enough knowledge and the time to monitor your investment on a daily basis, it may not be advisable for you. It would be much safer if you invest through a 3rd party, like insurance companies, wherein they have their own Fund Managers whose role is just to monitor the rise and fall in the stock market. For experts in the stock market, they'd rather do it themselves. But for most of us, it is better to put your investment in a company that has a good fund manager.
