One reason is because there are a lot of similarity between those days and the current ones. Another is that they are a warning to us!
In Timothy, we are warned of what the times and many people will be like:
“ But know this, that in the last days [a]perilous times will come: 2 For men will be lovers of themselves, lovers of money, boasters, proud, blasphemers, disobedient to parents, unthankful, unholy, 3 unloving, [b]unforgiving, slanderers, without self-control, brutal, despisers of good, 4 traitors, headstrong, haughty, lovers of pleasure rather than lovers of God, 5 having a form of godliness but denying its power. “-2 Timothy 3: 1-5
That is how the Days of Noah were. Most people turned to evil rather than to God!
Jesus told His apostles in Matthew 24:32, “Now learn this lesson from the fig tree: As soon as its twigs get tender and its leaves come out, you know that summer is near. “
No one but the Father knows the Day and Hour that Jesus will return, but Jesus warned us of the signs to look for and they are here. Will the End come, only the Father knows.
But irregardless, prayer and repentence might be a good idea. Lay your sins down at the foot of cross. Ask Jesus to forgive them and be your Savior. Start fresh 🙂
Because Jesus is Real and He is Coming Back. And our only hope is in Jesus 🙂
