No, garee, it's not there. Nowhere in Scripture do we read that there were "wars, rumors of wars, famines, pestilences, and earthquakes all over the corrupted dying creation" in days of Noah.
What we have is you conflating what is written in Matt 24:6-7 with what is written in Matt 24:37.
You lack faith in Scripture so you add what you believe and end up with imagination of men.
Nope.
Sign ...
Matthew 24:15 When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place, (whoso readeth, let him understand: )
When the sign is seen ... flee into the mountains (vs 16) ... no going into the house to gather belongings, just go (vs 17-18) ... why? ... because then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be (vs 21).
Sign ...
Matthew 24:29-30 Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken: And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
So after the sign of the abomination of desolation standing in the holy place and the great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be, there will be another sign ... the sign of the Son of Man in heaven.
Sign ...
Matthew 24:32-33 Now learn a parable of the fig tree; When his branch is yet tender, and putteth forth leaves, ye know that summer is nigh: So likewise ye, when ye shall see all these things, know that it is near, even at the doors.
So, again, your assertion that "the last sign was the sign of Jonas" fails.
You just make stuff up and when your error is pointed out to you and proper interpretation of Scripture is provided, you refuse it. That is a "sign", garee. It points to your utter and complete lack of faith.
In Acts 15, they did not keep silent. Read the whole chapter. Paul and Barnabas were ministers to the gentile believers. There were certain of the sect of the pharisees who were believers who insisted that it was needful to circumcise them, and to command them to keep the law of Moses (Acts 15:5). The apostles and elders came together for to consider of this matter (Acts 15:6).
They had a discussion ... a debate ... almost like a court hearing ... and made a decision concerning gentile believers:
Acts 15:
12 Then all the multitude kept silence, and gave audience to Barnabas and Paul, declaring what miracles and wonders God had wrought among the Gentiles by them.
13 And after they had held their peace, James answered, saying, Men and brethren, hearken unto me:
...
19 Wherefore my sentence is, that we trouble not them, which from among the Gentiles are turned to God:
20 But that we write unto them, that they abstain from pollutions of idols, and from fornication, and from things strangled, and from blood.
The multitude having "kept silence" was so they could give "audience to Barnabas and Paul". The keeping silent had nothing to do with making "the apostles into gods in the likeness of men" as you claim. Each side kept silent as the other side made their case. And then the matter was decided.
