These signs should just be an encouragement to our faith and confirmation of our belief in the plan of Salvation laid down in the Holy Bible because they are completely outside of our control, aligning God's Word with external Worldly and Heavenly events as God's way of proving to man His existence and mans weakness and mortality in the scheme of known creation.
Fulfilled Bible prophecy.
It does not matter whether you believe or not, your opinion does not change the facts all around you, it just proves your ignorance and denial which is your own prerogative that you will take to the grave with you.
Then if you are a denier of the truth it will be too late and you will be hoping you were right because of the consequences of denying God's plan of Salvation for man whilst alive, as all those who have believed and followed live with the hope and expectation of what God has prepared for them in eternity.
If God can create creation then eternity is in His hands too.
